OK, we will do that and start using 2.10 API freely.

There are 2 major things I'm aware of as they are somewhat complicated I would like to hear from you about them:
* https://bugs.eclipse.org/bugs/show_bug.cgi?id=408505 - I think there is a nice workaround in the patch. But my testing made me think it's related with our fixed class size allocation. Anyway getting the workaround in is critical for GTK3 testing and I plan to push it soon for GTK3 only.
* https://bugs.eclipse.org/bugs/show_bug.cgi?id=407077 - This one is more complicated and would need deeper changes.

I don't have Java 1.5 feature I'm looking for. My thought was if noone really tests on older JVMs aren't we setting false expectations?
