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) attached

Bests, Björn
