When trying to open the Launch dialog (Run/Run...), I get no response from the
system but rather a NullPointerException in the log file. I suspect some missing
folders in the classpath to be the source of the error, but since the dialog
does not open I cannot verify that. The exact same Exception is thrown if I try
to start one of the programs in the list of my launch files. 
This problem occures for one program I try to start and not for others.

I even reinstalled Eclipse and removed and recreated the project. Nothing
helped. Do I have to remove my complete workspace also?
I am using Version: 2.0 - Build id: 200206271827.
