When I run Lucene core tests with IBM J9 1.6, some tests fail with zombie threads that could not be killed, eg:
[junit4:junit4] ERROR 0.00s J2 | TestIndexWriterDelete (suite) <<< [junit4:junit4] > Throwable #1: com.carrotsearch.randomizedtesting.ThreadLeakError: 1 thread leaked from SUITE scope at org.apache.lucene.index.TestIndexWriterDelete: [junit4:junit4] > 1) Thread[id=102, name=Thread-44, state=TIMED_WAITING, group=TGRP-TestIndexWriterDelete] [junit4:junit4] > at java.lang.Object.wait(Native Method) [junit4:junit4] > at java.lang.Object.wait(Object.java:196) [junit4:junit4] > at java.util.Timer$TimerImpl.run(Timer.java:247) [junit4:junit4] > at __randomizedtesting.SeedInfo.seed([C9014BCB129899BF]:0) [junit4:junit4] > Throwable #2: com.carrotsearch.randomizedtesting.ThreadLeakError: There are still zombie threads that couldn't be terminated: [junit4:junit4] > 1) Thread[id=102, name=Thread-44, state=TIMED_WAITING, group=TGRP-TestIndexWriterDelete] [junit4:junit4] > at java.lang.Object.wait(Native Method) [junit4:junit4] > at java.lang.Object.wait(Object.java:196) [junit4:junit4] > at java.util.Timer$TimerImpl.run(Timer.java:247) [junit4:junit4] > at __randomizedtesting.SeedInfo.seed([C9014BCB129899BF]:0) It looks like this is a JVM thread ... is there an "exceptions list" somewhere to ignore this thread? Or some other solution? Second, strangely, I see the "who tests the tester tests" hit real failures, eg: [junit4:junit4] FAILURE 0.01s J2 | TestReproduceMessage.testFailureBeforeClass <<< [junit4:junit4] > Throwable #1: java.lang.AssertionError [junit4:junit4] > at org.junit.Assert.fail(Assert.java:92) [junit4:junit4] > at org.junit.Assert.assertTrue(Assert.java:43) [junit4:junit4] > at org.junit.Assert.assertTrue(Assert.java:54) [junit4:junit4] > at org.apache.lucene.util.junitcompat.TestReproduceMessage.testFailureBeforeClass(TestReproduceMessage.java:173) [junit4:junit4] > at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) [junit4:junit4] > at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:60) [junit4:junit4] > at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:37) [junit4:junit4] > at java.lang.reflect.Method.invoke(Method.java:611) [junit4:junit4] > at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:45) [junit4:junit4] > at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) [junit4:junit4] > at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:42) [junit4:junit4] > at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:20) [junit4:junit4] > at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:28) [junit4:junit4] > at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:30) [junit4:junit4] > at com.carrotsearch.randomizedtesting.rules.SystemPropertiesRestoreRule$1.evaluate(SystemPropertiesRestoreRule.java:53) [junit4:junit4] > at org.junit.rules.RunRules.evaluate(RunRules.java:18) [junit4:junit4] > at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:263) [junit4:junit4] > at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:68) [junit4:junit4] > at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:47) [junit4:junit4] > at org.junit.runners.ParentRunner$3.run(ParentRunner.java:231) [junit4:junit4] > at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:60) [junit4:junit4] > at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:229) [junit4:junit4] > at org.junit.runners.ParentRunner.access$000(ParentRunner.java:50) [junit4:junit4] > at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:222) [junit4:junit4] > at org.junit.runners.ParentRunner.run(ParentRunner.java:300) [junit4:junit4] > at com.carrotsearch.ant.tasks.junit4.slave.SlaveMain.execute(SlaveMain.java:180) [junit4:junit4] > at com.carrotsearch.ant.tasks.junit4.slave.SlaveMain.main(SlaveMain.java:275) [junit4:junit4] > at com.carrotsearch.ant.tasks.junit4.slave.SlaveMainSafe.main(SlaveMainSafe.java:12) These are tests that intentionally set up a failure, and then confirm that the test framework catches that failure ... yet for some reason with J9 this turns into a real failure ... any ideas?
