Gerhard Petracek reassigned DELTASPIKE-1378: -------------------------------------------- Assignee: Thomas Andraschko > EntityManagerRefLookup returns null globalEntityManager when > lazyInitGlobalEntityManager is called by multiple threads > ---------------------------------------------------------------------------------------------------------------------- > > Key: DELTASPIKE-1378 > URL: https://issues.apache.org/jira/browse/DELTASPIKE-1378 > Project: DeltaSpike > Issue Type: Bug > Components: JPA-Module > Affects Versions: 1.9.0 > Reporter: Raymond Domingo > Assignee: Thomas Andraschko > Priority: Major > Fix For: 1.9.1 > > > *Situation* > If multiple threads invoke lazyInitGlobalEntityManager at same time and > lazyInitGlobalEntityManager isn't invoked before. Some of these threads might > end up with a null entitymanager, because lazyInitGlobalEntityManager isn't > synchronized (or this.globalEntityManagerInitialized = true is at wrong > place). > Might be *important* to fix this, because In rare situations this might break > your application and even cause inconsistent data. > *Problem* > entityManager is null after initialization is concurrently called > *Expected* > entityManager won't be null when initialized concurrently > > *PR* > [https://github.com/apache/deltaspike/pull/89] -- This message was sent by Atlassian JIRA (v7.6.3#76005)
