[jbosstools-issues] [JBoss JIRA] Commented: (JBIDE-1293) JMX console generates errors when server is down/changed/etc.

[Rob Stryker (JIRA)]

Rob Stryker commented on JBIDE-1293:
------------------------------------

First, I am unable to replicate ( I know, I know, you're tired of hearing that.)

But secondly, this should NOT be happening based on the code. 

In JMXTreeContentProvider, it declares that children are only present if the server's state is "STARTED".  If the server is stopped, stopping, or starting, the jmx tree has no children.  The JMXTreeContentProvider is what is responsible for *loading* the children via jmx. (It launches a thread to do it). Basically, if the server isn't "STARTED" then no new jmx queries should be launched. 

The only way this could be happening is if some of those threads were launched and took long enough to execute to allow you to stop the server before the execution of that jmx call was completed.  This, I feel, is exceedingly unlikely. 

I'll continue trying to replicate.
