Hi all, The newly added testcase `serviceability/jvmti/vthread/TestPinCaseWithCFLH/TestPinCaseWithCFLH.java` fails with `-Xcomp` jvm option. The jvm option `-Xcomp` will make `BackgroundCompilation` false. In this test, disable `BackgroundCompilation` will make `instrumentation` in `premain` throw `java.util.MissingResourceException` in some test environments. So, I think it's necessary add `-XX:+BackgroundCompilation` option for this test to make this test more robustness, to make this test run passed with `-Xcomp` option. Test-fix only, no risk.
