[jbosstools-issues] [JBoss JIRA] (JBIDE-18267) Errors when starting EAP 5.2 - problem with jmx agent

Rob Stryker commented on JBIDE-18267:
-------------------------------------

Can you verify what version of java you are running eap5.2 with?  

As far as I can tell, java version shouldn't matter at all. EAP 5.2 can run  on java5 through 7 (although 5 is no longer supported). We find all the proper java classes (MBeanServerFactory)  but the MBeanServerFactory can't find the class org.jboss.mx.server.MBeanServerBuilderImpl.

If I had to guess, I'd say this is something in the way jboss prior to as7/wildfly structured its classloaders. The agent jar , now running on the jboss server, just doesn't have access to org.jboss.mx classes, and there's no way around that. 

I believe this has nothing at all to do with zipped or unzipped deployment. 

I can try to investigate the java.* and sun.* packages to see exactly what's going on, but, this doesn't seem like something really easy to do.

> It's kind of strange, but it didn't happen at first. When I changed the server to compressed deployment, it started happening. So I wanted to check again in a new workspace. In the new workspace, I just added the server and start (with default - exploded wars) and it happened again.
