Running the 1.0 branch

Step 2 should include the url to svn in tr (you mentioned it in
another email in this list) and not the old technology svn.
The wikipage http://wiki.eclipse.org/SVN_Howto has to be updated.
I know the Equinox group is migrating the source to tr...

Could the DERBY_HOME be obviated by implementing Eclipse-RegisterBuddy
but then... I guess this would not be OSGi??? Is there and equivalent
to Eclipse-RegisterBuddy in OSGi??

The run configuration for the RCP has to be reset with the required
plugins since I am testing on Linux.

I got this error both in Windows and Linux:
