Re: [rules-users] Multi Access to Stateful Session
So it looks like a race condition.
There is one chink in the snchronizing armour of class MessageControl.
The Map excludedPositions (although in itself synchronized on its own
lock) is exposed via the getExcludedPositions. Thus, synchronization
between currentPosition and excludedPositions is broken. I can't say
whether this matters, but just try and add delegating methods to
MessageControl and remove getExcludedPositions. (And use a plain
HashSet - synchronization is provided by MessageControl.)
Obviously, rules will have to use something like
atExcludedPosition == true
when the Map is fully privatized.

A gap would have to occur somewhere but I am not sure how or why.
Since I am using the same data for each test case, the outcome should
be the same but 75% of the time to position stops at a random point
and thus allows messages to backup in memory
