Comment 1 Milos Kleint CLA 2011-06-27 07:38:10 EDT 
MavenPluginActivator.getDefault().getMavenConfiguration() is where the NPE appears. The code in stacktrace is called after MavenPluginActivator.stop() is being called and reference to the MavenPluginActivator static reference is nullified. 

Not sure if the proper solution is to not nullify the ref or check for null when calling MavenPluginActivator.getDefault()
