Description
Using QuickFixJ version 1.5.2-bd by camel-quickfix we're observing some odd test failures on JDK 7 profile of Apache Camel however the behaviour is nondeterministic as we see the failed tests only from time to time where all the tests of QuickfixjEngineTest do fail because of the same assert, but as already said only on the JDK 7 and just from time to time. Also we cann't reproduce the issue locally. As you see on the trunk currently we've disabled the assert on JDK7.
The stacktrace of the failed assert looks as the following:
java.lang.AssertionError: QFJ mbean should not have been registered at org.junit.Assert.fail(Assert.java:93) at org.junit.Assert.assertTrue(Assert.java:43) at org.apache.camel.component.quickfixj.QuickfixjEngineTest.assertDefaultConfiguration(QuickfixjEngineTest.java:569) at org.apache.camel.component.quickfixj.QuickfixjEngineTest.defaultAcceptor(QuickfixjEngineTest.java:161) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:601) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:45) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:42) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:20) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:28) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:30) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:263) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:68) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:47) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:231) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:60) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:229) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:50) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:222) at org.junit.runners.ParentRunner.run(ParentRunner.java:300) at org.apache.maven.surefire.junit4.JUnit4TestSet.execute(JUnit4TestSet.java:53) at org.apache.maven.surefire.junit4.JUnit4Provider.executeTestSet(JUnit4Provider.java:119) at org.apache.maven.surefire.junit4.JUnit4Provider.invoke(JUnit4Provider.java:101) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:601) at org.apache.maven.surefire.booter.ProviderFactory$ClassLoaderProxy.invoke(ProviderFactory.java:103) at $Proxy0.invoke(Unknown Source) at org.apache.maven.surefire.booter.SurefireStarter.invokeProvider(SurefireStarter.java:150) at org.apache.maven.surefire.booter.SurefireStarter.runSuitesInProcess(SurefireStarter.java:91) at org.apache.maven.surefire.booter.ForkedBooter.main(ForkedBooter.java:69)
Which corresponds to this revision of QuickfixjEngineTest.
Currently we've disabled this assert as you can see by the revision history of this class.
Please also note that QuickfixjEngine does properly register/unregister the MBean, see it's doStart & doStop methods. This component's documentation is here. Any hint or idea would be much appreciated. Please let us know if there's any more details you may need.
