Subject: Strange error while creating groups

Organization: GIP RECIA

Hello,

I am trying to stress test an extension of grouper that I have written and of course ... it crashes :-( .

It is no deterministic : this time it occurred after creating more than 4500 groups but sometime it happens after 300 group creations.
Initially I thought it was because of a bad use of the grouper sessions but I have corrected everything to use the callback mechanism.

I have joined the stack and the instruction which generates the exception is :

(in the method resetGroupMembersInternal)

@SuppressWarnings("unchecked")
final Set<Member> members = group.getImmediateMembers();

If someone has an idea of a direction to investigate, I would really appreciate because I am not very inspired...

Thanks,
Arnaud.
