Possible inconsistency with concurrent transactions during state transfer ------------------------------------------------------------------------- Key: ISPN-3287 URL: https://issues.jboss.org/browse/ISPN-3287 Project: Infinispan Issue Type: Bug Components: Locking and Concurrency, State transfer Affects Versions: 5.3.0.Final Reporter: Dan Berindei Assignee: Dan Berindei Labels: jdg620_dm, jdg62GAblocker It looks like there is a data race between the state transfer thread and a concurrent transaction in EntryWrappingInterceptor.commitEntryIfNeeded: tx: commitContextEntry() ST: stateConsumer.isKeyUpdated(k)? false tx: stateConsumer.addUpdatedKey(k) ST: commitContextEntry() We probably need some synchronization here, maybe using EquivalentConcurrentHashMapV8.computeIfAbsent().
