Albert Lee updated OPENJPA-1193: -------------------------------- Affects Version/s: 2.2.0 2.1.1 Fix Version/s: (was: 2.2.0) Remove fix version in preparation for 2.2.0 release. > Memory leak when using FinalizingBrokerImpl > ------------------------------------------- > > Key: OPENJPA-1193 > URL: https://issues.apache.org/jira/browse/OPENJPA-1193 > Project: OpenJPA > Issue Type: Bug > Components: kernel > Affects Versions: 1.2.0, 1.2.1, 2.1.1, 2.2.0 > Environment: All environments where the finalizing broker is used > Reporter: David Minor > Assignee: Donald Woods > Fix For: 1.3.0 > > Attachments: fix-finalizing-broker-memory-leak.patch > > > When FinalizingBrokerImpl is used, AbstractBrokerFactory uses a set backed by > java's ConcurrentHashMap to keep track of brokers, rather than a weak > reference org.apache.openjpa.lib.util.concurrent.ConcurrentReferenceHashSet > as it did previously. This can lead to a memory leak if the brokers are never > removed from the Set. > The change was originally checked in by Patrick Linskey in revision 653000 > with the comment "Improve concurrency by actively managing > AbstractBrokerFactory's broker set when using non-finalizing brokers. Credit > goes to Arunabh Hazarika for identifying the bottleneck and prototyping this > solution." > Changing the _brokers Set back to a weak reference ConcurrentReferenceHashSet > fixes the memory leak. -- This message is automatically generated by JIRA.
