Hi,
I just installed a fresh Europa Fall Maintenance zip.
After importing my preferences I kicked a clean build and received
thousands of build errors.
Various types can't be found although they are there and have been found
with the previous installation.
I restarted several times, kicked clean builds even more often -- no effect.
VERY WEIRD: While I was typing this text all of a sudden (>2 minutes
after my last action in Eclipse)
*some* of the build errors simply disappeared. Not as result of a build!
Unfortunately there were 228 errors
left (also illegal errors) that did not disappear automagically. Stupid
me tried a full clean build again and now
I have again >2400 errors as before. Once more: All of them without reason.
When I press F3 on an unresolved class it *does* jump to the definition!
Usually I'd say JDT is completely broken and revert my installation to
the previous which I just renamed.
But I only tried a new installation because the previous one started
frequently showing OutOfPermGenSpace
errors and crashed and disappeared completely and without any
premonition. Simply unacceptable.
This behaviour started after I used UpdateManager to update installed
features. No idea if it really relates to that
or to which feature in particular it relates.
BTW. the effect that after several minutes some build errors go away
persists. while typing it happened a second time.
I'm only developing plugins so it could also be caused by PDE but how
should I know?
What shall I do?

Yes, all types (classes and interfaces) in my own code.

It might the the case that I have WTP or parts of it installed if they
are part of RCP EPP.
Other wise not. And I don't have web projects. My projects are all pure
bundle/plugin (i.e. PDE) projects.

-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256M
-vmargs
-Xms40m
-Xmx512m
Without actually profiling I think it didn't make a big difference
whether I use 256 or 128 MB as PermGenSpace.
