Compute launch button tooltip bug

[Saad Khawaja]

Hi

Eclipse version: 3.6.2.M20101201
Scala Ide version: 1.0.0.201102131804-milestones-M01
I had to pull this information from ${eclipse.home}/artifacts.xml,
since oddly Eclipse->About Eclipse was not working. I installed latest
eclipse & scala ide on 04/11.

I found an old eclipse bug related to this here
https://bugs.eclipse.org/bugs/show_bug.cgi?id=187617.

General description: I open a scala file in scala editor, select some
code cut it, save file causes compilation error, then hover mouse over
Run icon and get a eclipse pop up about 'Compute launch button
tooltip'.

Description of defect behavior:
1. Open .scala file in scala editor and scala perspective.
2. Select code block and do ctrl-x. The code block selected when cut
should cause compilation error.
3. Save file.
4. Hover mouse over Run icons, maybe even other icons.
Note: You may have to try this a couple of times, in different
combinations.
Effect :
See eclipse pop-up with text like 'Compute launch button tooltip' has
encountered a problem.
Here is text from detailed section of pop up
An internal error occurred during: "Compute launch button tooltip".
java.lang.IllegalArgumentException

Here is eclipse log output. I pasted the last two blocks of
exceptions.
