In replicated mode writeSkew check is executed only on coordinator ------------------------------------------------------------------ Key: ISPN-3678 URL: https://issues.jboss.org/browse/ISPN-3678 Project: Infinispan Issue Type: Bug Components: Transactions Affects Versions: 6.0.0.CR1 Reporter: Radim Vansa Assignee: Pedro Ruivo Priority: Critical Fix For: 6.0.0.Final Write skew check should be always performed on primary owner - however, in replicated and invalidation modes this is executed only on the coordinator (and primary owner). The bug is in ClusterDependentLogic.InvalidationLogic. As a result, two conditional commands (e.g putIfAbsent) may both succeed to set the value.
