Hi [~mapohl] and [~pnowojski], [~tanyuxin] and I have not been able to find
the cause of this problem for now. As far as I have investigated, a Java thread
might be blocked without an explicit "waiting to lock ..." hint if it involves
JNI calls like MonitorEnter/MonitorExit, internal locks like Semaphore and
CountDownLatch, or low-level synchronization primitives like
LockSupport.park(). However I did not find any match of these patterns in the
blocked thread's stack. Besides, it seems that Java's GC might also cause a
thread to be in blocking status, so we are not even sure there are blocking or
deadlock issues to resolve.
Given that we could not reproduce this error in our local environment, nor have
we found a similar error in Flink CI history, it seems that the error is a
low-probability issue that can be temporarily ignored. Could we mark this issue
as low priority for now and maybe revisit it when we have more inputs on
exceptions like this?

[~mapohl] [~pnowojski] Sorry for the late reply. I tried to reproduce the
issue, but it can not be reproduced in my local environment. I think it may be
an occasional case with a low probability. I and [~yunfengzhou] will continue
investigating the cause.

[~mapohl] [~pnowojski] I'll try to figure out the cause of this problem.
FLINK-33743 is not supposed to affect Flink's behavior when using bounded
blocking shuffle, but anyway I'll look into this.

[~mapohl] I haven't made any modifications to this area of code since a very
long time and I unfortunately recently don't have much time to investigate this
kind of issues. I would suggest to ping someone else. Maybe authors of the most
recent change to this test file: FLINK-33743

[~piotr.nowicki] (because it's networking; feel free to delegate)

someone help with investigating the cause of the issue?
