             Summary: Invalidation mode caches with pessimistic transactions may result in stale remote locks
                 Key: ISPN-2549
                 URL: https://issues.jboss.org/browse/ISPN-2549
             Project: Infinispan
          Issue Type: Bug
          Components: Locking and Concurrency
            Reporter: Adrian Nistor
            Assignee: Adrian Nistor


An invalidation mode cluster with two nodes A and B. Node A is coordinator.
Putting a key on node B results in a remote lock being acquired on A. But the lock on A is not released when the TX commits. Subsequent attempts to lock the key on A will fail with TimeoutException.

The key aspects to reproduce this are: 
1. pessimistic locking
2. the transaction starts on a node different than the coordinator

This scenario does not involve any state transfer, so it should not be related to the already known issues with stale locks caused by state-transfer.
