Not sure if this is Java 19 specific, or if it can be recreated, but adding to the Java 19 plan since it's discovered there.

babsingh · 2023-01-04T16:48:02Z

@thallium please do a preliminary triage: try to reproduce the failure (locally or in a grinder), develop a theory and probable cause for it.

babsingh · 2023-01-16T20:25:30Z

@thallium Please try a 300x grinder with the below parameters to reproduce the issue. It will run the test 50 times on 6 different machines. Thus, increasing the chances to reproduce the failure.

@babsingh https://hyc-runtimes-jenkins.swg-devops.com/job/Grinder/30458/ still unable to reproduce, not sure if I'm doing anything wrong.

babsingh · 2023-01-17T17:47:06Z

https://hyc-runtimes-jenkins.swg-devops.com/job/Grinder/30458/ still unable to reproduce, not sure if I'm doing anything wrong.

Both grinders are run correctly. The second grinder only runs the test with the following JVM options: -Xjit -Xgcpolicy:gencon -Xnocompressedrefs. The failure has either been fixed or very difficult to reproduce. @pshipton Shall we close this issue until it is seen again?

pshipton · 2023-01-17T18:25:47Z

Ok, closing until it's seen again.
