[infinispan-issues] [JBoss JIRA] (ISPN-5568) KeyAffinityService race condition on view change

KeyAffinityService race condition on view change ------------------------------------------------ Key: ISPN-5568 URL: https://issues.jboss.org/browse/ISPN-5568 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 5.2.11.Final Reporter: Dennis Reed KeyAffinityService#getKeyForAddress runs in a tight loop looking for keys: {noformat} queue = address2key.get(address) while (result == null) result = queue.poll() {noformat} KeyAffinityService#handleViewChange clears and resets the queue list on membership change: {noformat} address2key.clear() for each address map.put(address, new queue) {noformat} If a view change comes in after getKeyForAddress gets the queue, and the queue is empty, it will get stuck in a tight loop looking at the wrong queue forever while new keys are added to the new queue.
