I've recently begun migrating my RCP application from Eclipse 3.7 to Eclipse 4.4.
It is a Wizard based application (so I'm not actually using any of the Eclipse views or perspectives).
After importing my projects into Eclipse 4.4, I found that launching the product failed with lots of missing dependencies.
I went into the Run Configuration, and changed it to use all plugins in the workspace.
After that, the UI loads, but I can't click on anything at all. The entire UI appears frozen. In addition, in the top right hand corner, there is are truncated minimize/maximize icons that weren't there before, making me suspect it's being treated like a View or something, but I don't know how to verify that.
The menu options are still there, and work as expected.
When I run it, I see no errors in the console logs.
I do see the messages at the bottom of the post.
Searching about them hasn't given me much info on why they are occuring. One post suggested it was because org.eclipse.e4.ui.workbench.addons.swt was missing, but I made sure that particular plugin was present.
For a problem like this, where would I start?
I'm not familiar with e4, so I'm not too sure where to look for resources either.
My goal is to get my application to work on e4 with the least effort, so I though the E3 compatibility bridge would be best, but I haven't had any luck with it.

Hi,
your error makes me thinking about two possibilities:
- the cached target platform is corrupted and some classes are missing for org.eclipse.e4.tools.emf.ui --> try to reload the Target Platform
- there are still some missing plugins/services/imported packages. --> try to launch the application with an OSGi console (-console option) and try to start some bundles you might have more information of potential dependencies issue.
