Subject ActiveMQ error browsing via JMX
Date Wed, 17 Oct 2012 14:05:43 GMT
We are getting this error when trying to browse a queue via JMX. Everything
was working fine until this morning when we failed over from the master to
the slave. Now, we are unable to run QueueViewMBean browse to look at the
queue contents.   I don't see anything in the archive that is related and am
confused about why this started.
