-----------------------------------
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.
