Hi folks,

We saw a clinit deadlock with Log4j 2 and virtual threads recently. It's
common for libraries to use a mix of static and instance field loggers, so
seems particularly vulnerable to this kind of deadlock at startup.

I don't recall reading what you have planned for clinit pinning, so thought
I'd pass on this potentially common real-world deadlock and ask what you
have in mind for addressing this limitation.

Cheers,
Danny

The changes to preempt when a virtual thread must wait for a class to be 
initialized (by another thread) have been in the loom repo for sometime. 
This addresses the common cases. Patricio has JDK-8369238 [1] currently 
in review and should be in main line (and JDK 26 EA builds) soon.

Hi Danny,

I have recently read https://bugs.openjdk.org/browse/JDK-8369238 shared by
others, which could be relevant

Hope that helped,
Franz

Hi Danny,

I see a couple of FJP workers that don?t seem to be carrying a virtual 
thread blocked on clinit. Do you have the full stacktraces? If 
available, the native stack traces would also be useful to verify the 
entry point into the VM for the ones blocked at clinit.

Thanks,
Patricio

Hi Patricio

In our scenario, we encountered a similar issue that appears to stem from the same root cause. I?m happy to share the case details.

The problem arises in our custom class loader: when we use Logback to log messages, Logback attempts to acquire a lock during write operations. Meanwhile, a virtual thread that?s in the process of class initialization gets pinned&nbsp;to its carrier thread. As a result, other virtual threads attempting to use the same class end up being blocked with the message:
"Waited for initialization of <class&gt; by other thread".

These waiting threads also get pinned to their carrier threads ? but crucially, they do not enter&nbsp;<clinit&gt;. This creates a deadlock-like situation where:

One ForkJoinPool (FJP) worker thread is trying to acquire Logback?s lock.

Other FJP workers are waiting on a non-existent ObjectMonitor&nbsp;(likely due to the pinned thread holding the monitor and not progressing).

Interestingly, the stack traces appear to be in normal Java code, which makes the root cause non-obvious at first glance.

Hi&nbsp;Danny,

I&nbsp;see&nbsp;a&nbsp;couple&nbsp;of&nbsp;FJP&nbsp;workers&nbsp;that&nbsp;don?t&nbsp;seem&nbsp;to&nbsp;be&nbsp;carrying&nbsp;a&nbsp;virtual&nbsp;
thread&nbsp;blocked&nbsp;on&nbsp;clinit.&nbsp;Do&nbsp;you&nbsp;have&nbsp;the&nbsp;full&nbsp;stacktraces?&nbsp;If&nbsp;
available,&nbsp;the&nbsp;native&nbsp;stack&nbsp;traces&nbsp;would&nbsp;also&nbsp;be&nbsp;useful&nbsp;to&nbsp;verify&nbsp;the&nbsp;
entry&nbsp;point&nbsp;into&nbsp;the&nbsp;VM&nbsp;for&nbsp;the&nbsp;ones&nbsp;blocked&nbsp;at&nbsp;clinit.

Thanks,
Patricio

Just on this observation. I think your output/thread dump is from a 
build of JDK 21. It has been improved since then if you try JDK 25 then 
it will clearly delineate the stack trace of the carrier from the stack 
trace of the mounted virtual thread. If a virtual thread is waiting for 
another thread to initialize a class then has the "- waiting on the 
Class initialization monitor for XXX" at the frame where the virtual 
thread is waiting.

Yes, this is the issue addressed in JDK-8369238 for the common 
initialization paths. (Note that the initialization lock of a class is 
implemented using an internal Java monitor, so this is probably the one 
you are observing).

I?m confused about this stacktrace because I don?t see the <clinit> on 
the stack. If you could send the stacktraces of all threads, including 
the native stacks, that would be helpful.

The core pool size on that host was 4, so I assume those were compensated
workers? I don't have the original thread dumps I'm afraid, was quite a few
weeks ago now.

Subject: JDK 26 EA builds: changes to avoid pinning while waiting for class
 initialization
Message-ID: <6d1ac8ed-8645-b018-d33f-493107060cd7@oracle.com>

The latest JDK 26 EA builds [1] now include the changes from JDK-8369238 
[2]. With this update, a virtual thread that tries to initialize a class 
already being initialized by another thread will, in most cases, be 
unmounted from its carrier while waiting. Previously, the virtual thread 
would remain pinned to its carrier while waiting for the other thread to 
execute the class initializer.

This will help avoid pathological cases that can lead to deadlocks, in 
particular, those where all carriers are pinned by virtual threads 
waiting for another thread to execute a class initializer, while the 
thread executing the class initializer blocks or waits on something that 
requires a virtual thread to execute.

For now, the changes address the most common initialization paths 
described in JDK-8369238, but this might be extended in the future. As 
such, testing and feedback would be greatly appreciated, especially for 
those who have run into this issue on real-world applications.

Thanks,
Patricio

Subject: Significant degradation of Thread.sleep with virtual threads in JDK
 25 vs JDK 21
Message-ID: <GVZP280MB03792EBD9E7DCEE2F1A9E8A0FDD5A@GVZP280MB0379.SWEP280.PROD.OUTLOOK.COM>

Hey,

I believe I have found a bug with JDK 25 and virtual threads, but will need some guidance in what information I need to provide in order to file a bug.

Short version: after changing from JDK 21 to JDK 25, doing Thread.sleep(1) in a virtual thread now sometimes takes up to 60 seconds (!).

Long version:

I recently updated an application from Java 21 to 25 and started seeing a very negative performance impact.

The application in question runs ca 20 long running virtual threads which basically does the following:

while (true) {
    doTrivialWork();
    Thread.sleep(1);
    semaphore.acquire();
}

I.e. do trivial work, sleep 1 ms, wait on a semaphore to be woken by another thread, and then loop again. After long investigation I finally realized that it was the Thread.sleep that sometimes took significantly longer with Java 25 than Java 21.
So I timed it, basically just this:

while (true) {
    doTrivialWork();
    var start = System.nanoTime();
    Thread.sleep(1);
    var end = System.nanoTime();
    System.out.println("delay=" + (end - start));
    semaphore.acquire();
}

And let it run >1 million times.

With JDK 21 and either virtual threads or platform threads, or with latest JDK 25 and platform threads, it works fine and the Thread.sleep(1) finishes according to the following:

99,5% finish within 2 ms
0,4% finish within 4 ms
Worst case 80 ms

But with latest JDK 25 and virtual threads, it?s significantly worse:

98,0% finish within 2 ms
0,3% finish within 4 ms
0,5% taking over 1000 ms
A few hundred occurrences over 60 seconds (!)

The only change between these runs is JDK version and platform vs virtual threads.

Increasing jdk.virtualThreadScheduler.parallelism and jdk.virtualThreadScheduler.timerQueues makes no difference.
There are no jdk.VirtualThreadPinned or jdk.VirtualThreadSubmitFailed events in JFR.

Additional information:
The application is running in a pod on k8s with 1 CPU allocated to it.
No additional arguments for the JDK.
CPU utilization is less than 15%.
GC happens very infrequently (many minutes apart).

Thanks for the mail. Do you have a standalone test that uses the loop in 
your mail that we could use to study this?? The timer support has 
changed significantly twice between JDK 21 and JDK 25. From your mail 
then it could be a pathological case that leads to starvation, or it 
could be related to recently reported bug [1].

Thank you.
Unfortunately I've been unable to reproduce it locally outside of our runtime environment, but I do have a reliable reproducer there.

Would it help if I test this also with JDK 24/23/22?

Otherwise I can wait until JDK-8370887 is fixed (next release of JDK 25?) and test again then.

Regards,
Christian

My two cents: whatever you do to narrow it down will be helpful. I wonder
if along with testing on other JDKs you could also provide a bit more
information on that k8s node and the image you use. You could also build
the simplest image on which the issue is reproducible, and which only
contains publicly available components. If so, you could then share it.

If you can see if it reproduces with JDK 24 then it would narrow this 
down. It would also be useful to capture the output from running `jcmd 
<pid> Thread.vthread_scheduler` a few times while it executes as this 
includes info on delayed tasks.

It's possible it is related to JDK-8370887 but if all the sleeps are 
sleep(1) and there is no interrupt/cancellation then there may not be 
replacing going on to observe that issue. It may of course be that the 
picture is more complicated. In any case, expect a JDK 26 EA build soon 
with a fix to that issue.

You mentioned it reproduces in a single CPU environment. It's possible 
that is relevant although your message said you also test with 
jdk.virtualThreadScheduler.parallelism set so that might rule it out.

Does it have to be Thread.sleep(1) or is even Thread.yield() slow?

Subject: Question About PR #27802 and JDK 25 Backport
Message-ID: <CAJ_HiMt2y_oS4sKsC45mCR+Zso0h-L2SzmcJZyvB_ohYD7St9A@mail.gmail.com>

Hi team,

Great work on https://github.com/openjdk/jdk/pull/27802? the improvement to
virtual-thread behavior during class initialization is very helpful.

I?d like to ask whether there are any plans to *backport this fix to JDK
25?*

Any plans to improve Class.forName for virtual-thread workloads, especially
for Spring users?

Thanks again for your work on Loom.

Best regards,
Mengyang Li

A backport to 25 is unlikely. For now we mainly look to hear feedback 
from people testing the changes and identify any additional pain points 
in this area.

Not yet, but we can consider adding it to the roadmap if it proves to be 
a common issue. Has this call caused deadlocks in your application?

Thanks,
Patricio

I have tested with latest JDK 24 and do *not* see the issue there, only on JDK 25.

I have attached the output of running that jcmd every 15 seconds when the issue happened on JDK 25.

The jcmd output log covers 15:38:00 to 15:48:00. I saw the problems in my application between 15:40:00 and 15:45:45.

Thank you.
Unfortunately I've been unable to reproduce it locally outside of our runtime environment, but I do have a reliable reproducer there.

Would it help if I test this also with JDK 24/23/22?

Otherwise I can wait until JDK-8370887 is fixed (next release of JDK 25?) and test again then.


If you can see if it reproduces with JDK 24 then it would narrow this down. It would also be useful to capture the output from running `jcmd <pid> Thread.vthread_scheduler` a few times while it executes as this includes info on delayed tasks.

It's possible it is related to JDK-8370887 but if all the sleeps are sleep(1) and there is no interrupt/cancellation then there may not be replacing going on to observe that issue. It may of course be that the picture is more complicated. In any case, expect a JDK 26 EA build soon with a fix to that issue.

You mentioned it reproduces in a single CPU environment. It's possible that is relevant although your message said you also test with jdk.virtualThreadScheduler.parallelism set so that might rule it out.

Subject: Virtual vs platform performance at 10K HTTP requests
Message-ID: <CAG-0zZdM-L-f3UOMfatnMsL7Rpxs3dW-9Xx_ypzK23GLuSVNng@mail.gmail.com>

Hi,

I?m seeing some strange behaviour with virtual threads on JDK 25, and I?m
hoping someone here can point me in the right direction.

I?m running a benchmark comparing virtual threads and platform threads.
When issuing 10K HTTP requests, the virtual thread version consistently
stops making progress at around ~8100 requests. After that point, it only
makes small bursts of 100 to 1000 additional requests occasionally. This
happens with every iteration of the benchmark. CPU usage reflects this:
during the virtual thread benchmark all cores stay mostly idle (1?2%). The
platform thread version, on the other hand, completes 100K+ requests
without issues. I can reproduce this on macOS and Linux using both JDK 24
and 25.

The code I?m using: https://github.com/davidtos/Loom_REST_benchmark

Maybe I?m missing something obvious, but I can?t explain this behaviour. My
current hypothesis is that issuing 10K concurrent requests causes something
(HTTP client, networking, or scheduler) to saturate differently under
virtual threads but that doesn?t fully explain the periodic request bursts.

Hope someone can help me out.

Thanks in advance!

Kind regards,
David

Your platform test is limiting to at most 4 outstanding requests.

The virtual thread one is uncapped so you have probably hosed the server and it can?t respond, or you?ve run out of memory, or connections, ?. lots of possibilities?.

I assume it also benefits from being able to use HTTP persistent 
connections.

The benchmark using virtual threads is very different, it tries to 
establish 10k connections in a burst. Do you know what connection 
backlog is used by Tomcat? It may require adjusting net.core.somaxconn 
(kern.ipc.somaxconn on macOS) and other settings. ~8100 may be 8k and 
maybe there is something in the Tomcat or Spring connection that 
controls this.

Hi,

There seems to be a limit causing a 12-30 second delay after establishing
~8K connections too quickly. 10K platform threads do not see or reach this
limit.

The simplest workaround I found was adding System.out.println("1"); right
before making each request. The synchronized lock is probably doing the
heavy lifting here. This makes the platform and virtual threads perform
about the same.

Increasing the server-side Tomcat settings also resolves the stalling:

   - server.tomcat.accept-count=10000
   - server.tomcat.max-connections=20000
   - server.tomcat.threads.max=500
   - server.tomcat.threads.min-spare=50

However, with these higher server limits, I'm seeing different throughput
characteristics:

   - Platform threads: 2.3 ops/s
   - Virtual threads: 0.9 ops/s (about half the speed)


I assume it also benefits from being able to use HTTP persistent
> connections.
>

Just trying to understand, does that mean that virtual threads don't have
this? Because running Socket Statistics in the background showing 17K
established connections while running virtual threads vs 140 when using
platform threads.

At this point I am just trying to understand where this delay is coming
from and why virtual threads trigger this.

Thanks in advance!

Kind regards,
David

A more honest comparison would be using a Executors.newCachedThreadPool() so it is also unlimited connections, or using a Semaphore with 4 permits around the virtual

Persistent connections avoid needing a separate TCP connection for each 
request. LoomBenchmark's FixedPlatformPool appears to use a thread pool 
with 4 workers so it gets to benefit from the having the cached 
connection. Tomcat probably has more configuration to limit/configure 
the number connections to keep alive, probably 100 or 200 by default. 
LoomBenchmark.java's virtualThreadExecutor is a completely different 
test. It attempts to establish 10k concurrent connections, it's probably 
causing connections to be closed and re-established at each iteration.

Hi all,

Thanks for the explanations. I now realize I was looking at it the wrong
way. I treated it as a workload of 10K requests that needed to be executed,
without realizing how much persistent connections would affect the outcome.
Using a semaphore with the same number of permits as platform threads
brought the performance much closer to the platform thread version.

Thanks again for the insights!

Kind regards,
David

Thanks, that rules out a signalling issue. Are you able to test with JDK

I did both with David's benchmark. Of course, the semaphore is the way to go. With default Tomcat settings, 200 or 2000 permits work fine, and then virtual threads give significantly better throughput than a small number of platform threads. As one would expect.

But back to those 10000 simultaneous connections. As David observed, left unthrottled, virtual threads do really poorly. In my experiment, *much* more poorly than platform threads, when using a Executors.newCachedThreadPool().

I am wondering why that would be, and whether it is something that is worth addressing, because it seems like something that people could run into in practice. FWIW, I stumbled upon https://bugs.openjdk.org/browse/JDK-8360046 which addresses a somewhat similar scenario.

Cheers,

Cay

All of this is explained by Little's Law primarily, and Universal 
Scalability Law secondarily.

10k or 50k+ concurrent connections shouldn't be an issue but it may 
involve tweaking a number of sysctl.conf/equivalent settings to get 
there. Elliot Barlas published a fun project at one point where he had 
several million TCP connections with 2 virtual threads per connection.

I think the issue we are discussing here is partly about storming the 
server with SYN packets to establish the TCP connections. Servers 
typically have rate limiting and other mitigations to avoid SYN flood 
attacks. This is why we were asking about the connection backlog and 
other configuration. It's possible the thread pool bench isn't going to 
see this because it's using synchronous/blocking APIs to establish the 
TCP connection and so the number of outstanding connects in progress is 
limited by the size of the thread pool.

The other part that seems relevant is that the protocol in the 
benchmarks is HTTP/1.1 which supports persistent connections, 
essentially re-use of a TCP connection if possible to avoid creating a 
new TCP connection for each HTTP server. There's another layer of 
configuration here. I don't know Tomcat's defaults but it is likely that 
it keep 100 or 200 connections alive for future HTTP requests. Once the 
concurrency exceeds this then it's likely there is a new TCP connection 
established for each request. The thread pool bench is 4 threads and 
likely well below the maximum number of persistent connections.

So yes, moving from thread pools to virtual threads may shine light on 
the "next" concurrency bottleneck, the bottle hidden by limiting the 
number of threads. The guidance that we've given at conferences and in 
the JEPs is to use a semaphore/equivalent to limit concurrent at the 
right level of granularity, be that number of concurrent database 
connections or whatever it might be.

That one is an over subscription issue that arises with producer 
starting a lot of virtual threads that "do nothing". It helps us to 
reduce the gap between ForkJoinTasks that "do nothing" with virtual 
threads that "do nothing".

This is it. The OS out of the box does not expect to deal with that many connection requests in a short period - especially OSX. It often appears to be a DoS attack if not reconfigured.

We are using only one EC2 (no horizontal scaling) with virtual threads to
output video streaming, and we needed to tweak the OS configuration to make
it work to support a lot of concurrent connections, we have seen 10K
concurrent connections no issue using Spring Boot and JDK 24. Something to
take a look https://docs.gatling.io/concepts/operations/

Hi,

One last thing I wanted to share. I ran the benchmark with two servers and
one client (three machines). Using the following code to switch between
them. Both servers stop logging between 4400 and 5100 requests (between 8K
- 10K total) when using virtual threads. The platform threads continue
running. I hope this rules out the servers being an issue, a single target
reaches 8K. It is probably something within the client that cannot handle
more than 8K requests.

if(r.nextBoolean()){
    String response1 =  fetchJavaNineStyle(URI.create("
http://192.168.1.44:8080/v1/delay/" + plan.delay).toURL());
    blackhole.consume(response1);
} else {
    String response1 =  fetchJavaNineStyle(URI.create("
http://192.168.1.122:8080/v1/delay/" + plan.delay).toURL());
    blackhole.consume(response1);
}

Subject: "Memory leak" caused by WorkQueue#topLevelExec

Hello community,

Sorry if this is the wrong place to discuss internal classes such as the ForkJoinPool. If so, please, excuse me and point me in the right direction.

At my company, we have experienced an unfortunate memory leak because one of our CountedCompleter was retaining a large object and the task was not released to the GC (I will give more details below but will first focus on the FJP code causing the issue).

When running tasks, the FJP ends up calling [WorkQueue#topLevelExec](https://github.com/openjdk/jdk/blob/c419dda4e99c3b72fbee95b93159db2e23b994b6/src/java.base/share/classes/java/util/concurrent/ForkJoinPool.java#L1448-L1453), which is implemented as follow:

final void topLevelExec(ForkJoinTask<?> task, int fifo) {
while (task != null) {
task.doExec();
task = nextLocalTask(fifo);
} }

We can see that it starts from a top-level task task?, executes it, and looks for the next task to execute before repeating this loop. This means that, as long as we find a task through nextLocalTask??, we do not exit this method and the caller of topLevelExec? retains in its stack a reference to the first executed task - like [here](https://github.com/openjdk/jdk/blob/c419dda4e99c3b72fbee95b93159db2e23b994b6/src/java.base/share/classes/java/util/concurrent/ForkJoinPool.java#L1992-L2019). This acts as a path from the GC root, preventing the garbage collection of the task.
So even if a CountedCompleter did complete its exec / tryComplete / etc, the framework will keep the object alive.
Could the code be changed to avoid this issue? I am willing to do the work, as well as come up with a test case reproducing the issue if it is deemed needed.

In our case, we were in the unfortunate situation where our counted completer was holding an element which happened to be a sort of head of a dynamic sort of linked queue. By retaining it, the rest of the growing linked queue was also retained in memory, leading to the memory leak.
Obvious fixes are possible in our code, by ensuring that we nullify such elements when our operations complete, and more ideas. But this means that we have to be constantly careful about the fields we pass to the task, what is captured if we give lambdas, etc. If the whole ForkJoinPool could also be improved to avoid such problems, it would be an additional safety.

Thank you for reading the mail
Cheers

Olivier

Hi Olivier,
Appreciate sharing your initiative with us. In my understanding of your
case -

?something that behaves like a concurrent linked queue (or a lock-free
stack, or a tree of work items) where new work items are dynamically linked
together via object references.?

Let me know if this is reflective of your case.

Cheers,
Vince

Thank you Vincente for looking at it.

Just to be extra clear and not let you reflect on a non-problem, the "something behaving like a queue" is one of our internal classes. We are very satisfied with it, we have no intention of changing it.
And we know that the best way to avoid leaks with this structure is to avoid retaining references to the nodes. So, in a sense, storing them as fields in a CountedCompleter is a risk. We though that it was a small risk as the completer would be GC soon after its execution. And it happens that cases exist where it is not.
The obvious fix for us it clean the completers once their job is done. It is just massive, but meh, if we have to, we will do it.

The sharing is mostly because it can impact many over codebases, beyond ours, possibly even Loom.

Cheers
Olivier

Hi. I am not really sure what you expect to happen here. When you fork/join the system needs to maintain a reference to the top-level task in order to determine when it has completed and thus the executor is available for the next. You see that in the ForkJoin JDK code you linked.

So, the easiest solution is to make the task payload clearable - you can?t clear the task but you can clear the heavy payload - allow it to be GC?d.

Or, make the running of the subtasks async without a reference to the heavy payload so the top-task can return and be garbage collected.

It sounds like a misuse of FJ - as if you are running your own FJ infra inside of ForkJoin - might as well take ForkJoin out and write a custom executor that doesn?t hold the task reference.

This is better suited to concurrency-discuss at openjdk.org.
