>                 URL: https://issues.apache.org/jira/browse/GEODE-152
>             Project: Geode
>          Issue Type: Bug
>            Reporter: Darrel Schneider
>            Assignee: Darrel Schneider
>            Priority: Minor
>
> See: https://builds.apache.org/job/Geode-nightly/164/testReport/com.gemstone.gemfire.management/MemberMBeanAttributesDUnitTest/testOSAttributes/
> Caused by: java.lang.NullPointerException
> 	at com.gemstone.gemfire.management.internal.beans.MemberMBeanBridge.fetchJvmThreads(MemberMBeanBridge.java:1331)
> 	at com.gemstone.gemfire.management.internal.beans.MemberMBean.fetchJvmThreads(MemberMBean.java:153)
> 	at com.gemstone.gemfire.management.MemberMBeanAttributesDUnitTest$6.run(MemberMBeanAttributesDUnitTest.java:236)
> When fetchJvmThreads calls getThreadInfo it needs to deal with slots in the returned array being null. The javadocs in getThreadInfo says:
>      * If a thread of the given ID is not alive or does not exist,
>      * <tt>null</tt> will be set in the corresponding element
>      * in the returned array.
> So this is a bug in: com.gemstone.gemfire.management.internal.beans.MemberMBeanBridge.fetchJvmThreads()
