Eclipse 3.x RCP application editor [message #870291]

I've a working Eclipse 3.x RCP application in which I've an editor which creates the EditorSite as below -

......
EditorSite editorSite = new EditorSite(
editorRef,
editor,
(WorkbenchPage) PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage(),
(EditorDescriptor) ed );
.......

Since the EditorSite signature has changed in Eclipse 4.x I got the below compilation error -
"The type org.eclipse.e4.ui.model.application.ui.basic.MPart cannot be resolved. It is indirectly referenced from required .class files"

Isn't the 3.x RCP application expected to work as it is in e4 without any code changes? What am I missing? Some dependencies?

Thanks

Why are you using EditorSite and not IEditorSite? You are referencing
internals here!

The compilation problem is one of compiletime vs runtime classpath [1]
which means that projects compiling against internals in 3.x will work
without problems.

Not sure we should reexport our model in 4.x though. Could you please
file a bug including this informations.

A 3.x RCP app that uses the API will compile and run in both 3.8 and 4.2.

If you use internals (and you're not supposed to) it will not compile in 4.2 and even if you build it on 3.8, it will not run in 4.2 (you'll get runtime errors)

Just saw this you are never supposed to create an EditorSite instance
yourself this code is completely wrong.

What is the reason you are doing this! It can't never work and could be
haven been broken in any Eclipse 3.x release not only 4.x.
