Pessimistic transactions can lose their locks when the primary owner changes ---------------------------------------------------------------------------- Key: ISPN-5076 URL: https://issues.jboss.org/browse/ISPN-5076 Project: Infinispan Issue Type: Bug Components: Core, State Transfer Affects Versions: 7.0.2.Final, 7.1.0.Alpha1 Reporter: Dan Berindei Assignee: Dan Berindei Priority: Critical Labels: 7.0 Fix For: 7.2.0.CR1 In a pessimistic cache, if a transaction {{T1}} has a {{put(k, v)}} operation and the primary owner of the key is the originator, the lock is acquired on the originator but it is not replicated to on the backup(s). If one of the backup owners becomes the primary owner, it will allow another transaction {{T2}} to lock (and update) key {{k}} before it receives the one-phase prepare command from the originator of {{T1}}.
