Subject [jira] Commented: (AMQNET-301) Session.CreateSession creates a thread that never gets disposed.
Date Wed, 05 Jan 2011 22:00:52 GMT

    [ https://issues.apache.org/jira/browse/AMQNET-301?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12977996#action_12977996

Kelly Elias commented on AMQNET-301:
------------------------------------

I haven't been able to try out the 1.5 version yet as the links for the client downloads of
the Apache.NMS.ActiveMQ don't appear to work yet. But all the previous versions up to 1.1
seem to have the issue. Once I can get the client dll, I'll give 1.5 a try.

> The Factory.CreateSession function creates a thread that never gets disposed.
> If you run the code in visual studio and step through each line you will notice that
on the first iteration of the loop two threads are created on the factory.CreateConnection
line. Only one is cleaned up. Then each iteration after one thread is created on factory.CreateSession
and is cleaned up correctly, but a second on is created on connection.CreateSession and is
not cleaned up. Every iteration will then make a thread on connection.CreateSession that does
not get cleaned up.
> Interesting, this occurs with every version I've tested except the old 1.1 version. That
version cleans up correctly.
