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.
