Re-adding invalidated node fails with invalidation + pessimistic locking ------------------------------------------------------------------------ Key: JBCACHE-1251 URL: http://jira.jboss.com/jira/browse/JBCACHE-1251 Project: JBoss Cache Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: 2.1.0.CR2 Reporter: Brian Stansberry Assigned To: Manik Surtani Scenario is one where a parent node represents a structural node, and then child nodes represent different data elements. Such data structures are set up on both caches, and then the parent node is removed (globally, via INVALIDATION) and re-added (locally) on one cache. This represents an attempt to clear the region -- removing a node and re-adding is one of the only ways to do this. On the second cache, the fact that the structural node is missing is detected, and an attempt is made to re-add it locally. This fails with pessimistic locking: 18:50:34,821 TRACE PessimisticLockInterceptor:71 - PessimisticLockInterceptor invoked for method MethodName: _put; MethodIdInteger: 1; Args: (null, /test/com/foo/test/ENTITY, null, true) 18:50:34,821 TRACE PessimisticLockInterceptor:292 -
