>          Components: Core
>    Affects Versions: 2.0.3.CR1
>         Environment: 2.0.3.CR1, JBoss 4.2.2, JDK 5
>            Reporter: Sanne Grinovero

> As confirmed by other people on the forum at http://seamframework.org/Community/ConcurrentModificationExceptionAfterProgrammaticLogin
> It is possible for ServerConversationContext to iterate on an EntrySet which is modified in the iteration block.
> I couldn't understand exactly in which scenarios it happens, but it's easy to patch the code
> to iterate on a copy instead (I'll attach the patch).
> I can't say if it's correct to make a copy, or if you should actually avoid the changes.
