[jdk11u-dev] RFR: 8236042: [TESTBUG] serviceability/sa/ClhsdbCDSCore.java fails with -Xcomp -XX:TieredStopAtLevel=1

[Zhengyu Gu]

Backport for parity with Oracle 11.0.15.

The original patch does not apply cleanly due to context difference. However, that patch is small, can be applied manually.

Test:

- [x]  Without patch, serviceability/sa/ClhsdbCDSCore.java test failed with -Xcomp -XX:TieredStopAtLevel=1, passed with patch.
