Subject Thread leak in Activemq 5.6
Date Sun, 16 Jun 2013 08:07:42 GMT
Dear all,


I found a thread leak issue during try activemq 5.6:
I create connection when sending message and close it once the sending finished.
Occassionally I restart activemq broker and found one thread generated with name "ActiveMQ
Connection Executor...".
For deep research, I restarted the broker several times and same number thread generated;
I attached the picture of my debug.
Could anybody give me some clues? I just want to know if this is a bug for ActiveMQ. The attachments
includes my applications and the debugging pictures.


It would be much appreciated if you make any suggestion!!!


Thanks in advance,
Zhuran Li
