> {{TestCallQueueManager#testSwapUnderContention}} fails occasionally on a test VM with
this assert.
> {code}
> java.lang.AssertionError: null
> 	at org.junit.Assert.fail(Assert.java:92)
> 	at org.junit.Assert.assertTrue(Assert.java:43)
> 	at org.junit.Assert.assertTrue(Assert.java:54)
> 	at org.apache.hadoop.ipc.TestCallQueueManager.testSwapUnderContention(TestCallQueueManager.java:193)
> {code}
> Although it appears unlikely, it is possible for the queue to be intermittently empty
while the putters and getters are running. The assert can be removed or coded differently.
