Re: [equinox-dev] ClassNotFoundException with, org.eclipse.osgi_3.3.0.v2

Oh, I forgot to mention that calculating uses has been part of the organize manifest functionality in 3.3. Check out the new and noteworthy for PDE (5th item down):

Great. I always wanted a button named after me in eclipse. Make it "do
the Karl thing" as label :-)

Well, the problem is that this would not be a feature enhancement it
would be a bug report. The tool generates incorrect meta-data. You
might not bite but your users may end-up with ClassCastExceptions
because the tool doesn't constrain the export packages correctly and
thus Class space consistency can not be ensured.
