JDK-8172015 - ConcurrentQueues/OfferRemoveLoops.java fails
Description
The following test failed in the JDK20 CI:

java/util/concurrent/ConcurrentQueues/OfferRemoveLoops.java

Here's a snippet from the log file:

#section:main
----------messages:(7/230)----------

result: Error. Agent communication error: java.io.EOFException; check console log for any additional details

So we have a partial crash report in the stdout log and
a link to the replay_pid file. I'm going to start this bug in
hotspot/compiler for initial triage.

This is a Tier1 failure so it would normally start as a P2, but
it did not reproduce so I'm starting it as a P3.

I found much older unresolved bug for the same test: JDK-8172015 ConcurrentQueues/OfferRemoveLoops.java fails but the failure modes described in it don't match the failure mode in this bug.
