The way I understood this issue is that only if you use the as7 management startup poller the connection is being attempted at all.

MBean Explorer causes Eclipse crash when exposing management port but not using management poller ------------------------------------------------------------------------------------------------- Key: JBIDE-12770 URL: https://issues.jboss.org/browse/JBIDE-12770 Project: Tools (JBoss Tools) Issue Type: Bug Components: jmx Affects Versions: 4.0.0.Alpha2 Environment: JBT 4.0.0.Alpha2b OS X 10.8 Mountain Lion Reporter: Martin Malina Assignee: Rob Stryker Fix For: 4.0.x Under specific conditions Eclipse can crash/take 100% CPU. We've seen this before and it happened when there was no JMX connection but the MBean Explorer was trying to load the nodes anyway. This is a similar case. It would be good to have some sort of check before we start loading the MBeans.
