Race condition when automatically creating parent nodes during locking fails to get lock ---------------------------------------------------------------------------------------- Key: JBCACHE-1620 URL: https://issues.jboss.org/browse/JBCACHE-1620 Project: JBoss Cache Issue Type: Bug Security Level: Public(Everyone can see) Components: Locking Affects Versions: 3.2.9.GA Reporter: Dennis Reed Assignee: Dennis Reed Attachments: JBCACHE-1620-test.zip Bug/race condition in PessimisticUnversionedNode#addChildAndAcquireLock. If two threads try to create the same node at the exact same time, one thread creates it and gets a write lock. The other thread does not create a node, but returns the previously created node and does not lock it. The only caller PessimisticNodeBasedLockManager assumes the node was both created and locked after the call returns.
