The test task description is:

Run test open/test/jdk/:jdk_lang with macosx-x64-debug with -Xcomp -XX:+CreateCoredumpOnCrash -ea -esa -XX:CompileThreshold=100 -XX:+UnlockExperimentalVMOptions -server -XX:+TieredCompilation -XX:+VerifyOops

so I'm starting this bug in hotspot/compiler for initial triage.
