Description Remi Schnekenburger CLA 2010-11-15 10:25:53 EST 
In some cases, org.eclipse.papyrus.editor.PapyrusMatchingStrategy can lead to a ClassCastException when trying to navigate from java files.

Use case:
- Install Papyrus in Eclipse
- Open a java file
- Try to navigate in the file using Ctlr+click. this opens a stack trace.

The problem is located in the class PapyrusMatchingStrategy from the plugin org.eclipse.papyrus.editor. The first line contains a untested conversion of the editor input as a IFileEditorInput... A test is performed later, but this is too late.
