Could you provide the reproducible test case? And do you test with OpenJDK before?

OpenJDK8u202b08 fails with this testcase either. I'd like to suggest you to submit this case to the upstream OpenJDK bug tracking system, https://bugs.openjdk.java.net/

alternatively, Dragonwell community may help to raise OpenJDK bugs with your consent. Thanks!

yansendao commented 5 years ago

Dragonwell community can help me to raise OpenJDK bugs and then close this issue. Thanks very much.

Created bug at: https://bugs.openjdk.java.net/browse/JDK-8221605 But I found that OpenJDK11 passed the test.
