Description of problem: EAP 6.2.0.ER6 JGroups 3.2.12.Final Note: I have seen this in some previous versions as well and was looking into it: UDP variants of org.jgroups.tests.LargeStateTransferTest.testStateTransferX often fail with: Error Message requester view is [requester|0] [requester], but should have 2 members Stacktrace java.lang.AssertionError at org.jgroups.tests.LargeStateTransferTest._testStateTransfer(LargeStateTransferTest.java:82) at org.jgroups.tests.LargeStateTransferTest.testStateTransfer1(LargeStateTransferTest.java:57) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.testng.internal.MethodInvocationHelper.invokeMethod(MethodInvocationHelper.java:80) at org.testng.internal.InvokeMethodRunnable.runOne(InvokeMethodRunnable.java:46) at org.testng.internal.InvokeMethodRunnable.run(InvokeMethodRunnable.java:37) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:439) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:303) at java.util.concurrent.FutureTask.run(FutureTask.java:138) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:895) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:918) at java.lang.Thread.run(Thread.java:662) The issue is not in JGroups, but rather in the testsuite and it has already been fixed in upstream so component upgrades will solve this in time.
NOTE: A number of EAP clustering issues relate to failures in the JGroups testsuite. Some of these failures relate to tests of features of JGroups which are not used by EAP. As of EAP 6.3, a modified version of the JGroups testsuite (JGroups version 3.2.13) is being executed which excludes tests of JGroups features which are not used by EAP. Only the testsuite has been modified/fixed; the product is unchanged. The list of features can be found here: https://mojo.redhat.com/docs/DOC-938761 EAP 6.3 Clustering issues relating to failures in the JGroups testsuite are being closed if they relate to features not used by EAP.
