Has been only seen on linux-aarch64-debug so far. The arguments list seem to be a pre-requisite as well:

-Xcomp -XX:+CreateCoredumpOnCrash -ea -esa -XX:CompileThreshold=100 -XX:+UnlockExperimentalVMOptions -server -XX:+TieredCompilation -XX:+VerifyOops

The stack trace and error message:

----------System.err:(24/1537)----------
 stdout: [[0.023s][warning][gc,ergo] NewSize (20480k) is greater than the MaxNewSize (10240k). A new max generation size of 20480k will be used.
