Description Robert Allen

Using Eclipse Galileo. I've updated all software and plug-ins and it makes no difference. Uninstalled maven integration plug-in and reinstalled it and makes no difference.

What steps will reproduce the problem?
1. start eclipse
2. exception thrown during jdt initialization
3.

"Plug-in org.maven.ide.eclipse.jdt was unable to load class
org.maven.ide.eclipse.jdt.internal.JDTCompilationParticipant"...

This appears to be a Maven issue, not an Eclipse issue; the Maven plugin is apparently unable to initialize its compilation participant, due to an unhandled NPE.  Please report this to the Maven folks via the Maven bug tracking system.
