Tabbing / traversing Controls in Eclipse sometimes stops working on mac os x. After you get stuck you cannot tab either backward or forward. When this problem occur you are always at a ToolBar (I haven't seen it on any other Control).

Reproducible: Always

Steps to Reproduce:
1. Start a fresh Eclipse.
2. Select a new workspace.
3. Close the welcome screen.
4. Start pressing tab (and shift-tab). You will see how the focus traverses to different Controls, as expected.
5. Switch to the Debug perspective.
6. Press tab a few times. You will get stuck at "Skip All Breakpoints". This is a bug. However, you can Shift-Tab away again. 
7. Switch back to the Java Perspective.
8. Now you can tab or shift-tab back and forth, until you get to "New Java Package". Now you cannot navigate away with tab or shift-tab. You are stuck.

Some debugging yielded that we are dealing with a ToolBar. Composite.keyDown() will see that this ToolBar has focus, but it is not a CANVAS, so super.keyDown() will be called. Control.keyDown() will conclude that hasKeyboardFocus(id) is false (seems that a ToolItem has the keyboard focus?), so nothing will happen here either.
