VM crash when adding new instance variable to MethodDictionary

Hi everyone,

we got the following issue.

Problem:
I get a VM crash when adding a new instance variable to the MethodDictionary
class.
Happens on 5.2 as well as on trunk.

Expected behavior:
Any of the following
1. It works
2. You get an error, that you may not change the instance variables of
MethodDictionary (as done on Collection and add a hint in the class comment

Steps to reproduce:
1. Add an instance variable to the MethodDictionary class
2. Save the change

Stacktrace:
(is from 5.2 but happens on trunk as well)

Bests,
Björn
