The failed assertion is on line 666:

{code:java|title=TestReplicationHandler.java}
666:    assertEquals(1, 
Integer.parseInt(getSlaveDetails("timesIndexReplicated")));
667:    String timesFailed = getSlaveDetails("timesFailed");
668:    assertEquals(0, Integer.parseInt(timesFailed != null ?  timesFailed : 
"0"));
{code}

{{getSlaveDetails()}} prints out the properties it retrieves as JSON following 
"SHALIN:" -- see the log excerpt above.  {{timesIndexReplicated}} is 2 instead 
of 1 because there was an unexpected replication failure: {{timesFailed}} is 1; 
if the assertion at line 666 were not there, then the one asserting zero 
replication failures, at line 668, would fail.
