Subject Re: Do you know when ActiveMQ Session threads dies ?
Date Fri, 03 Jul 2009 12:41:49 GMT

I think that I have some news.

The problem is more complex than I wrote initially (I wanted to be clear).

In fact, I have two ActiveMQ connections initialized in the same "main" JVM.
One with an embedded broker, the second with a distant broker embedded in an
"other" JVM. Some threads didn't die when I want to shutdown my "main" JVM
in this condition :
- I stop the "other" JVM gracefully. 
- OnException is called on the "main JVM", but I don't close sessions nor
close this connection on the main JVM, since I think that this is done
automatically.
- I want to stop the "main" JVM by closing session on the embedded
connection, closing connection, and shutdown the embedded broker.

It is in this configuration that some sessions are not closed and my process
doesn't want to stop gracefully.

I think that threads that don't die are finally affected to the broken
connection.
I can see that "ActiveMQ Connection Worker" thread associated with my broken
connection is always active.

What is the best way to deal with this problem ?

Thank you
Eric-AWL
