since a few days we encounter the following error for any dialog or wizard page we try to open in windowbuilder:

full stacktrace attached.
btw, if I select "reparse" after that error occured, the following error is raised:
- Code: Select all
java.lang.NoClassDefFoundError: Could not initialize class javax.swing.UIManager
full stacktrace attached as well.
any hints what might be the problem? strange thing is, it didn't happen like one week ago. unfortunately I can't really remember, what system changes (or eclipse installation changes) have been done in the meantime.
WB version is 7.0.0 running within eclipse 3.5 under windows xp 64.
best regards,
Andreas
