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 Affects Versions: 5.2.0.Beta4 Reporter: Adrian Nistor Assignee: Adrian Nistor Fix For: 5.3.0.Final Attachments: InvalidationModePessimisticLockingIssueTest.java 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.
