NullPointerException in InactivityMonitor?
I'm moving to 4.0-RC2, but keep getting these when my broker is running.
I guess the InactivityMonitor is to blame, as they happen periodically
and during inactivity. There are no connections made to the broker. A
bug, or an issue with my setup?

My broker config is very simple:
<beans xmlns="http://activemq.org/config/1.0">
<broker useJmx="false">
<transportConnectors>
<transportConnector name="ssl" uri="ssl://ocicat.csc.fi:61616" />
</transportConnectors>
</broker>
</beans>
Re: NullPointerException in InactivityMonitor?
Posted by James Strachan <ja...@gmail.com>.
I've just patched the NullPointerException to avoid this happening;
though I don't understand why your connection was receiving a
PartialCommand; these are only used with udp and multicast transports
- which you shouldn't be using from your configuration.
I wonder do you have different jars on your client and broker?
