Description cschneider4711 2007-01-23 20:54:13 UTC 
After using (on a somewhat young and freshly installed NB with Ent.Pack / 
Vis.Pack and Prof./Pack) update center and including the beta updates on the 
next startup I received error messages regarding CVS support. On the next few 
startups of NB I receive the following exception and the startup procedure 
hangs completely (unable to start NB).

Comment 1 cschneider4711 2007-01-23 21:02:44 UTC 
I was able to make NB start again after disabling the following modules 
manually in their XML files:

~/.netbeans/5.5/config/Modules/org-netbeans-modules-vcs-advanced.xml
~/.netbeans/5.5/config/Modules/org-netbeans-modules-vcs-profiles-clearcase.xml
~/.netbeans/5.5/config/Modules/org-netbeans-modules-vcs-profiles-cvsprofiles.xml
~/.netbeans/5.5/config/Modules/org-netbeans-modules-vcs-profiles-pvcs.xml
~/.netbeans/5.5/config/Modules/org-netbeans-modules-vcs-profiles-teamware.xml
~/.netbeans/5.5/config/Modules/org-netbeans-modules-vcs-profiles-vss.xml

So it seems to be some incompatibility with the above modules. Maybe the 
module loading system could be enhanced to allow to continue the startup 
process by asking the user if the offending module(s) that caused the 
exception should be disabled for the next startup.

Keep up the good work,
Chris
