> Failed on a private build of git rev 4708d4e182f89c6a391fcad8bac854f929717685: 
> {code}
> at com.gemstone.gemfire.management.ClientHealthStatsDUnitTest.testClientHealthStats_SubscriptionEnabled(ClientHealthStatsDUnitTest.java:133)
> [snip]
> Caused by: java.lang.NullPointerException
> 	at com.gemstone.gemfire.management.ClientHealthStatsDUnitTest.put(ClientHealthStatsDUnitTest.java:394)
> {code}
> This is the code that has the NPE:
> assertEquals(r1.getEntry(k1).getValue(), client_k1);
> The context makes clear that r1 is not null so the NPE is caused by getEntry(k1) returning
null. The line right before this did a put of k1:
> r1.put(k1, client_k1);
> so perhaps a concurrent destroy can happen that causes the intermittent NPE?
