      Since the jdb test crash in JVM/TI GetThreadLocalStorage()
      I'm starting this bug off in hotspot/jvmti.

      The failing task's description is:

      Run test :vmTestbase_nsk_jdb with macosx-x64-debug with -Xcomp -XX:+CreateCoredumpOnCrash -ea -esa -XX:CompileThreshold=100 -XX:+UnlockExperimentalVMOptions -server -XX:+TieredCompilation -XX:+DeoptimizeALot

      so there are some extra options involved.
