I don't know specifically about the draw2d.jar file, but GEF is licensed under the EPL:

You should also consult the licensing in general:

http://www.eclipse.org/legal/eplfaq.php
http://www.eclipse.org/legal/legalfaq.php

Note that you'll need to determine whether your plugin is a 'derivative work' or not, and if so, you may need to license your code under the EPL.

IANAL but my understanding is:

org.example contains 'draw2d.jar' from GEF, and thus org.example may be considered a derivative work, and thus must be under the EPL (including making source available)

org.example depends on org.eclipse.gef.runtime. In this case, only the org.eclipse.gef.runtime is under the EPL, and you're allowed to redistribute that unmodified under the EPL. org.example can be any license you choose.

For sanity (as much as anything else) you're probably better off shipping the standard built Jars under their own licenses and having a dependency between the two. Apart from anything else, if the GEF is updated then you can just update the plugin, and your plugin will take advantage of the bug fixes.

However, you should consult with proper lawyers because my understanding could be completely wrong ...

Alex.

questions about licensing are best in the newsgroup
"eclipse.foundation"

Personally I don't think there are any issues so long as you are not cutting
and pasting from GEF source or directly extending GEF classes. And I think
the latter may even be allowed.
