@ChangLu0607 are you using the recent jdk8 release branch?

@sophia-guo I believe that you are looking at an other failed test case. BiSheng JDK also pass this test case in adoptium. So I believe it may be a environment setting problem that makes the test case failed intermittently. And according to the modification from adopt openjdk community can make the test case more relible

Yes, I was looking at the other failed test case for another issue. The test passed in adoptium bisheng build. https://ci.adoptopenjdk.net/job/Test_openjdk8_bisheng_extended.openjdk_x86-64_linux_testList_1/28/testReport/jdk_jfr_event_oldobject_TestClassLoaderLeak/java/

I think it's a testcae bug for this fail.

Should we disable this testcase by add this testcase to openjdk/excludes/ProblemList_openjdk8.txt ?
