Subject [jira] [Commented] (GEODE-2647) ClientHealthStatsDUnitTest.testClientHealthStats_SubscriptionEnabled fails with NullPointerException
Date Wed, 15 Mar 2017 16:41:41 GMT

    [ https://issues.apache.org/jira/browse/GEODE-2647?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15926533#comment-15926533
] 

Kirk Lund commented on GEODE-2647:
----------------------------------

This failure is intermittent, but I don't see evidence of it being flakiness in the test.


It looks to me like region.getEntry(KEY1).getValue() should return non-null entry and value
to the thread that immediately before that invoked region.put(KEY1, VALUE1).
{noformat}
    Cache cache = (Cache) clientCache;
    Region<String, String> region = cache.getRegion(Region.SEPARATOR + REGION_NAME);

    region.put(KEY1, VALUE1);
    assertThat(region.getEntry(KEY1).getValue()).isEqualTo(VALUE1); <-- throws NPE!
