The code in Vera's post is how it should work. The bug is in our code
when 'null' is returned on refactoringContribution.createDescriptor().
This got fixed in 3.4 M1, but also needs to be fixed in 3.3.2
I filed https://bugs.eclipse.org/bugs/show_bug.cgi?id=205706
If you need this working in 3.3.1, instanciate the MoveDescriptor
yourself (This is only a workaround as the spec doesn't support this).
The second suggestion (using JavaMoveProcessor) is using internal
classes (see the 'internal' in the package name) and is not recommended.
There's no promise that this code will work in future versions.
