A DESCRIPTION OF THE PROBLEM :
When I try to open a project in netbeans 5.5.1, I get a nullpointerexception.
I've reported this to netbeans and it was closed as being your problem.
I've gone through your bug database and found the same stack trace and the bug was closed as "not a bug".  I'm wondering who is responsible for a correction for this problem or if it some type of environment problem.

 Following is a stack trace:
