Started my workbench this morning and was met with the following NPE. Sorry no additional steps to reproduce.

The root message of the exception is:

"Exception occurred in listener of pre Java resource change notification"

Somehow there was a change to a localization file for which we couldn't find a plugin model for.  Either there was a project that isn't a pde project that just happened to have the correct localization directory structure or something else caused the model lookup to fail.

I cleaned up the logic a bit and added a null check.  Fixed in HEAD.

Verified the check is in I20100804-0100
