Comment 1 Philipe Mulet CLA 2001-11-21 07:41:09 EST 
I have added protection against this crash. The #elements() enumeration wasn't 
protected from a case when asking again after it thinks it has no more elements.

However, I am intrigued about how this occurred. Do you remember what the 
classpath change was ? And also what were the extra project references (in case 
there was any) ?

The #remove function did left the ObjectSet inconsistent.
Fixed
