Bug 1022918

Description of problem:

EAP 6.1.1.ER7, 6.2.0.ER1, 6.2.0.ER6
Infinispan 5.2.7.Final

There is an occasional failure of org.infinispan.api.MixedModeTest.testMixedMode. It fails rarely and I have only seen it with ibm jdk 1.7 (and thus only on RHEL) but cannot guarantee that it only happens there.

Stacktrace
