Build M5

I'm trying to build a text editor which provides a (large) subset of the 
behaviour available in the CompilationUnitEditor.

This editor will be used to edit 'snippets' of Java code which control the 
behaviour of a flow, drawn in a diagram adjacent to the text editor.

I've had quite a bit of success subclassing AbstractTextEditor and using a 
JavaSourceViewerConfiguration to configure it.

However I've had to reach into jdt.internal packages for a couple of things. I 
would like these to be promoted to public classes.

They are:

org.eclipse.jdt.internal.ui.javaeditor.AddImportOnSelectionAction
org.eclipse.jdt.internal.ui.javaeditor.OrganizeImportsAction

I also use
org.eclipse.jdt.internal.ui.javaeditor.JavaEditorMessages.
so that I can use the same labels for my actions as the CU editor uses.

And I use
org.eclipse.jdt.internal.ui.text.correction.JavaCorrectionSourceViewer
so that I can get the CORRECTIONASSIST_PROPOSALS constant. (I'm not 100% 
certain that I need this one.)

I also need to provide a correctly typed IDocumentProvider to make content 
assist work properly. The only way that I've found to do this is:

setDocumentProvider((IDocumentProvider)JavaUI.getWorkingCopyManager());

This isn't really safe, since I'm relying on private knowledge that the 
working copy manager is also a dcument provider. I would like JavaUI to expose 
an API to access the CompilationUnitDocumentProvider (e.g. 
JavaUI.getDocumentProvider()).
