Another point is performance, especially start-up performance. This might not be important for the Eclipse SDK and for some huge business applications, but for ordinary RCP applications (like RSSOwl), this is very important. On my second computer, a Mac mini (Core 2 Duo T5600), Eclipse 3.6.2 takes 6.5 seconds to start, and Eclipse 4.2 M4 about 9.5+ seconds (both are warmed-up times).

Agreed - getting Eclipse 4 out with max performance and stability is the
most important thing. There are many areas to improve starting from
memory leaks to stuff like closeing of editors.

Hm - just tried and it worked

This is because Eclipse does some polling of certain context values in order to implement lazy plug-in activation. However, there is something inherently wrong with this approach. There should be some other mechanism that is triggered when context values have changed or might have changed.

If I read this correct they did not port their code from 4.x back to 3.x
but created their own RCP like framework which though I can understand I
think if they would have invested their time into EAP they would have
provided value to everyone.

I hoped this could help start the documentation process, but there's still no E4-related documentation in the Eclipse SDK's online help. Here's the bug with the outline: https://bugs.eclipse.org/bugs/show_bug.cgi?id=325654

Ideally, the existing and excellent book "Java Developer's Guide to Eclipse" should be updated (see http://www.amazon.com/Java-Developers-Guide-Eclipse-2nd/dp/0321305027/). However, it is obvious that this would require a *huge* effort and quite a few people.

I hope I can find some more time in next weeks to restart contributing
to Eclipse 4.x but doing my JavaFX stuff is high on my list as well.
