Issue

While migrating from EAP 6.4 to EAP 7.1.3 a memory leak on infinispan EJB cache has been detected.
One of the differences between EAP 6.4 and 7.1 concerns EJB passivation: file-passivation-store is replaced by an infinispan passivation-store.
We can see EJBs are removed from memory once the session times out. However the infinispan EJB cache keeps growing while it should be flat.
Upon disabling EJB passivation, we observe no more leak, so we suspect there is a leak in infinispan with respect to the EJB passivation feature.
