1. Open an editor.
2. Window > Open Perspective > Debug
3. Start spawning vertical stacks in the shared area with the 'Outline', 'Variables', and 'Breakpoints' view.
4. When there's only space left to just show the tab item and some of its content or so and you try to DND to in that area to make another vertical stack, you may eventually hit this IAE.

Comment 1 Nobody - feel free to take it

Tried but can not reproduce this. Since it a bit old I'm thinking it got fixed.
Remy can you still repro this?

Looks okay with I20121016-2240 on Windows 7. Although frankly, I don't remember what I was doing exactly. Too bad I didn't take a screenshot.
