Hi,
I'm using JMS with ActiveMQ in my junit tests and sometimes it hangs
inexplicabily.
I have noticed that this is followed by a NullPointerExcpetion detailed
here:
[[http://www.nabble.com/NullPointerException--on-ActiveMQConnection.close-tt18345477.html][link]
Are the two related ?
Following is part of the stack trace where con.start() is being called. Any
help or pointers will be appreciated.
Thanks,
Abhi
