TopologyAwareTwoNodesMapReduceTest.testCombinerDoesNotChangeResult fails randomly on my machine, with this stacktrace:

java.lang.AssertionError
	at org.infinispan.distexec.mapreduce.BaseWordCountMapReduceTest.testCombinerDoesNotChangeResult(BaseWordCountMapReduceTest.java:217)

I think it's because it's comparing Integer objects with == instead of equals(). Actually it would be best to use Assert.assertEquals(), I tried to find the expected and actual values in the log but I wasn't able to.
