At some point when launching Eclipse I see an
IncompatibleClassChangeError. I'm attaching the log.
This might mean a libgcj linker bug, or it might imply
that some Eclipse class is not properly recompiled (e.g.).

What version of eclipse is this?
I just tried to reproduce this bug with the proposed FC4 update (in
updates-testing) but I cannot. If you can try out this update  and verify
that this issue is indeed fixed, I would appreciate it.
yum --enablerepo=updates-testing update eclipse-pde (or whatever)
I definitely don't see this any more.
