I was just setting up xmlBuddy (the plugin) to be the default editor for
the .project and .classpath files, and when closing the preferences
dialog, eclipse threw an NPE into the log (below):.
I then tried doing it step by step and closing the dialog each step, and
it worked.
Here's the NPE stacktrace if anyone's interested:
