             Summary: DistSyncCacheStoreNotSharedTest fails randomly
                 Key: ISPN-2619
                 URL: https://issues.jboss.org/browse/ISPN-2619
             Project: Infinispan
          Issue Type: Bug
          Components: Test Suite
    Affects Versions: 5.2.0.Beta5
            Reporter: Dan Berindei
            Assignee: Mircea Markus


DistSyncCacheStoreNotSharedTest fails (pretty rarely) with this exception:

{noformat}
09:29:51,069 ERROR (testng-DistSyncCacheStoreNotSharedTest:) [UnitTestTestNGListener] Test testAtomicPutIfAbsentFromNonOwner(org.infinispan.distribution.DistSyncCacheStoreNotSharedTest) failed.
java.lang.AssertionError
	at org.infinispan.distribution.DistSyncCacheStoreNotSharedTest.testAtomicPutIfAbsentFromNonOwner(DistSyncCacheStoreNotSharedTest.java:293)
{noformat}

What happens is that at the end of the previous test there is a get() that goes remotely, and one of the ClusteredGetCommands (to node C) is delayed. The test framework then clears the cache store and the data container on node C, but the get command already had the entry in its context and will write it to the data container when it finishes executing, so that the data container is not empty when testAtomicPutIfAbsentFromNonOwner starts.
