FC4: Eclipse Fails to Save

[mlenz at new.rr.com]

Hi,
I just did a fresh install of FC4.  Now when I try to edit files in an
Eclipse C++ project that I was using in FC3 (using Eclipse 3.0), it
can't save.  I first get an error "Save Failed: null" and then every
subsequent save before closing Eclipse gives me this error "Save
Failed:org.eclipse.core.internal.utils.UniversalUniqueIdentifier".  When
I look at the .log file it looks like it can't find the class
UniversalUniqueIdentifier.  Here is a snippet of the .log file:

!ENTRY org.eclipse.ui 4 4 2005-06-14 18:10:10.455
!MESSAGE Save Failed

!ENTRY org.eclipse.ui 2 0 2005-06-14 18:10:10.456

...

Is anyone else seeing this problem or know of a solution?

Thanks.
