Eclipse project with sample code

The following exception occurs when disposing a form containing a scrolled composite.

Error stack:
TypeError: Cannot call method 'getFocusRoot' of null

This happens since 2012-03-30. With Juno M6 it works fine.

Steps to reproduce:
Run the attached rwt application, click on the button two times and then on the empty space. The above exception appears (at least in the js console) and clicking the button has no effect anymore.
