> An object instance can be managed by at most one EntityManager (at a time). The pattern used in the JPACacheStore's process method is illegal.
> The solution is to clear the primary EntityManager and pass the detached data to the second EntityManager.
> There is a comment about something similar being needed in MySQL when there is a single connection; I'd rather check to have multiple connections available to avoid deadlocks.
