Description Brad Maxwell 2015-01-23 01:37:19 UTC 
Calling remote JMX server method such as getMBeanCount() by several remote clients leads to random NullPointerExceptions on the server side such as: 

[0m[33m18:38:11,612 WARN  [org.jboss.remotingjmx.protocol.v2.ServerCommon] (pool-2-thread-12) Unexpected internal error: java.lang.NullPointerException

Comment 6 Jan Martiska 2015-02-13 08:10:09 UTC 
Given that the newly found NPE is tracked under BZ 1192181, closing this. The original NPE is fixed in EAP 6.4.0.ER2.
