[jira] Updated: (HARMONY-5821) [drlvm] stress test jpda.jdwp.scenario.MIXED001.MixedTest001 FAILED

Posted by "Gregory Shimansky (JIRA)" <ji...@apache.org>.
     [ https://issues.apache.org/jira/browse/HARMONY-5821?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Gregory Shimansky updated HARMONY-5821:
---------------------------------------

    Estimated Complexity: Advanced
                 Summary: [drlvm] stress test jpda.jdwp.scenario.MIXED001.MixedTest001 FAILED  (was: [drlvm][jdwp] stress test jpda.jdwp.scenario.MIXED001.MixedTest001 FAILED)

The bug is not related to JDWP or JVMTI. The NPE happens in VM that is performing a role of debugger (kind of like Eclipse). It is not debugging any application, it is giving commands over JPDA to the debuggee. So the problem is not related to debugging, it is related to an execution of a Java application.

The bug looks like an enumeration problem to me. In the calling method MIXED001.MixedTest001.testMixed001 the variable refTypesArray is clearly not null since on the line 390 the code calls refTypesArray.getLength method and no NPE happens. But in the called method StressTestCase.checkClasses it becomes null on the line 2082. So enumeration problem is one of the reasons of NPE.

But there may be some different crash in the execution of code at the line 2082. Any crash in Java code is treated as an NPE, it may be unrelated to the refTypesArray.
