Subject: Unexplained hangs on Windows arm64
Message-ID: <CAHY-eHsvyi4ycVmYq_Yw3Zx2ofUfr1k22ZAXLTf5BVDMRaZLJA@mail.gmail.com>

Hi everyone,

I'm currently investigating indefinite hangs of the build system Bazel that
occur only on Windows arm64 (
https://github.com/bazelbuild/bazel/issues/28520) - Linux, macOS as well as
Windows x64 are unaffected. Bazel runs itself via an embedded JDK 25 and
I've been able to reproduce the same hangs on 25.0.2.

The hangs occur while Bazel downloads external dependencies using
HttpURLConnection in virtual threads created by a
VirtualThreadPerTaskExecutor. I captured JSON thread dumps (
https://github.com/user-attachments/files/25097968/threads.json and
https://github.com/user-attachments/files/25102540/threads2.json are
examples, but I can provide more) which all seem to have the following in
common:
1. Virtual threads are blocked in either very short synchronized blocks
(e.g. SynchronizedMap methods) or WEPoll#ctl.
2. There are enough carrier threads available throughout (the machine has 8
cores).

I don't know how to explain why there is no progress in these situations -
the thread dumps don't seem to point to an obvious deadlock, but the
program never makes progress again after getting into this state.
WEPoll#ctl led me to think that this may be related to a subtle deadlock
issue affecting the Go runtime (
https://www.ntkernel.com/a-rare-cancelioex-hang-in-go-on-windows/), but I
then found thread dumps such as the second one above that don't include an
such frames.

Is there anything special about the Loom impl on Windows arm64 that could
explain this behavior?

Fabian

Hi Fabian,

This is likely due to https://bugs.openjdk.org/browse/JDK-8373630. I see 
you are testing on 25.0.2 but the fix is in 25.0.3. Could you see if it 
reproduces with a newer build?

I would share my reflections
1. All "system" VT, "system" means f.e.created  by Structured Concurrency,
automatically ends and never become unreachable
2. Only application VT can become unreachable, f.e. when a blocking queue
became unreachable
3. Every VT is naturally GC-able, because only diagnostic flag
trackAllThreads saves unreached VT from release
4. Diagnostic is important
5. If trackAllThreads use weak reference, it can impact GC, as
potentially there can be millions of VT

Maybe it is worth to consider `Thread.ofEphemeral()` tracked by weak
reference
1. Implementation effort is minimal, there will be two maps of VT instead
of one
2. Performance effort is zero, because only intentional, application VT can
increase GC time (Volenti non fit iniuria)
3. Diagnostic still works

Hi Patricio,

thank you for the pointer!

I verified that the hang is fixed with the latest JDK 27 EA. I haven't
found an EA build of 25.0.3+1 yet, but I will try to build my own and
validate that the issue is fixed.

I suspect that you are attempting to address something different to what 
Alan had in mind here. I interpret Alan's response to be about 
performance of the grouping, unrelated to whether ephemerality is a 
thing or not.

(The inherent problems linked to ephemerality is discussed at length in 
this thread)
