Great thinking. Personally I would think that if jBPM uses ' completed' like this internally it should be a reserved and therefore disallowed name. The fact that jBPM handles it gracefully is strange. In all cases where you do not have a 'completed' by yourself, you get one for free. In other cases you don't. Some people might start searching for a bug but in the end will find out there is this default weird behaviour.
