JPACacheStore is associating same objects to multiple EntityManagers -------------------------------------------------------------------- Key: ISPN-4539 URL: https://issues.jboss.org/browse/ISPN-4539 Project: Infinispan Issue Type: Bug Components: Loaders and Stores Reporter: Sanne Grinovero 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.
