Subject [jira] [Commented] (AMQ-5098) ActiveMQ fails and starts complaining lock is already held for the JVM
Date Thu, 13 Mar 2014 16:57:47 GMT

    [ https://issues.apache.org/jira/browse/AMQ-5098?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13933532#comment-13933532

Arthur Naseef commented on AMQ-5098:
------------------------------------

Thanks Gary.  Yes, this is with trunk. I have been seeing it for a little while, but always
putting it off.  This time, I decided to get it captured.

I'm thinking there is a race condition.  I'll try start=false and see if that helps.

Any ideas on how I can see what Spring is up to without adding debugging to the Spring code?
 I tried increasing logging for spring to debug, but that didn't help.
