@dsouzai is this the same issue as #17311 ?

Yeah I think this is the same issue; looks like the shutdown sequence interrupted the compilation thread before it had a chance to connect to the jitserver instance.

@dsouzai After #17313 shouldn't the output show that the server is still alive?

[2023-05-07T01:15:24.141Z] Test result: FAILED

This set of tests works in the following way:

  1. Enable JITServer specified Pre-Checkpoint but not explicitly enabled Post-Restore launches the criuJitServerScript.sh script which starts the jitserver instance, runs the org.openj9.criu.OptionsFileTest, and then stops the jitserver instance.
  2. Enable JITServer specified Pre-Checkpoint: Check no connection in Pre-Checkpoint checks the vlog generated pre-checkpoint
  3. Enable JITServer specified Pre-Checkpoint: Check connection in Post-Restore Verbose Log checks the vlog generated post-restore

Because these tests involve both jitserver and criu, it's kind of tricky to test the state of things pre-checkpoint and post-restore.

All that said, I'm not really sure what's going on here. If the jitserver instance didn't exist, I would've expected to see a message in the post-restore vlog that showed a failed connection. However, I don't see any such message, which implies that the JVM didn't even bother trying to connect. I'm not sure something like this wouldn't have shown up in the PR tests unless there's something specific to x86. EDIT: not sure that's a valid argument because literally every other build (including x86) passed.

I believe this is another instance of #17367 (since the test before the cat vlog "test" passed).
