Description

TestCallQueueManager#testSwapUnderContention fails occasionally on a test VM with this assert.

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)

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.
