RFR: 8336284: Test TestClhsdbJstackLock.java/TestJhsdbJstackLock.java fails with -Xcomp after JDK-8335743

Hi all,
Test TestClhsdbJstackLock.java/TestJhsdbJstackLock.java fails with -Xcomp after [JDK-8335743](https://bugs.openjdk.org/browse/JDK-8335743). I think the new failures was testcase bug.

The change has been verified by -Xmixed/-Xcomp(c2)/-Xcomp -XX:TieredStopAtLevel=1(c1), only change the testcase, no risk.
