NPE thrown when accessing EventRouterStatistics when statistics are disabled #95

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
When statistics collection is disable, if one tries to read them through JMX 
(eg: jmx-console, accessing 
http://127.0.0.1:8080/jmx-console/HtmlAdaptor?action=inspectMBean&name=org.mobic
ents.slee%3Aname%3DEventRouterStatistics) a NullPointerException is thrown.

Stacktrace:

2013-07-19 08:40:23,129 ERROR
