Description Justin Spadea

This is due to an old Sun JRE bug regarding locking in the classloader (see http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4670071)

The workarounds we've been suggesting:
Use an IBM JRE if you have one
Add the following VM args if you have to use a Sun JRE: -XX:+UnlockDiagnosticVMOptions -XX:+UnsyncloadClass

A couple of us have been running with a proposed fix for about a week now and it seems to have resolved the deadlock without introducing other issues. The following have been modified:

InitializeSystemPartsJob.java
MofEglPlugin.java

Description of change:
MofEglPlugin no longer loads the system parts when the plug-in is activated. Clients must explicitly invoke its initializeSystemPackages() method to load the system parts. The method fred(), which was only used to get the plug-in to load if not loaded already, has been removed.
