using build N20070510-0010, after changing my compiler compliance settings and trying to switch to the build path page I got the following error:

Steps (not 100% reproducable):

1. change compiler compliance on an existing java project to something lower than it was (in my case I went from 1.5 to 1.4 compliance). Also seemed to happen if I changed from project specific settings to workspace default which was lower (1.5 -> 1.4).
2. click 'Yes' to do a rebuild now when asked
3. try to navigate to another properties page
