[Pharo-project] Issue # 1498 "Collections should not accept non integer indexes"

I'm trying to follow the directions given at: http://code.google.com/p/pharo/wiki/HowToContribute. However, after the SLICE asks for the first comment, it freezes the image and the small window "Writing definitions" stays at 50% progress and nothing happens then. So I'll resort to the alternative plan, which is to send the changeset to this list. On a core image update #11067 the Collection tests are all green. Running all tests show one error and two failures not related to the changed methods. -- Cesar Rabak
