Build: NetBeans IDE 6.8 (Build 200912041610)

OS: Windows XP

User Comments:
GUEST: I tried to open a project.
The main issue from end user point of view is that the project is impossible to work at all (I would understand if java source functionality was restricted or absent at all, but I couldn't even open a file - just nothing happens if I open the project)

Running NetBeans 6.8 on JDK5 and working with NetBeans sources (currenly prototypes repository, branch nbms-pack200-84852).
I`ve build the sources using JDK6 (ant clean build-nozip -Dcluster.config).
When I try to open any module sources (e.g. autoupdate.services) using NetBeans IDE (6.8) I get this exception.
I have also tried to clean ~/.netbeans/6.8/var/cache but that didn`t help.

Workaround is to delete nbbuild/nbproject/private/*.ser.
