Heath Thomann closed OPENJPA-2107. ---------------------------------- > ManagedCache conflict due adding an entity 2 times in the same query. > --------------------------------------------------------------------- > > Key: OPENJPA-2107 > URL: https://issues.apache.org/jira/browse/OPENJPA-2107 > Project: OpenJPA > Issue Type: Bug > Components: kernel > Affects Versions: 2.0.1, 2.1.0, 2.2.0 > Reporter: Mark Struberg > Assignee: Heath Thomann > Fix For: 1.2.3, 2.0.2, 2.1.2, 2.2.0 > > Attachments: OPENJPA-2107.patch > > > I have a complex query which creates the following error: > <openjpa-2.2.0-tiss-2-rexported nonfatal user error> > org.apache.openjpa.persistence.ArgumentException: Cannot load object with id > "26301". Instance > "at.ac.tuwien.tiss.curriculum.be.entities.DefaultCourse@6e267b76" with the > same id already exists in the L1 cache. This can occur when you assign an > existing id to a new instance, and before flushing attempt to load the > existing instance for that id. > FailedObject: at.ac.tuwien.tiss.curriculum.be.entities.DefaultCourse-26301 > at org.apache.openjpa.kernel.ManagedCache.add(ManagedCache.java:126) > at > org.apache.openjpa.kernel.BrokerImpl.setStateManager(BrokerImpl.java:4117) > at > org.apache.openjpa.kernel.StateManagerImpl.initialize(StateManagerImpl.java:391) > at > org.apache.openjpa.kernel.StateManagerImpl.initialize(StateManagerImpl.java:340) > at > org.apache.openjpa.jdbc.kernel.JDBCStoreManager.initializeState(JDBCStoreManager.java:378) > It seems that this entity gets loaded from the db twice in the same query. > While hitting the problem, the StateManagers have the following _flags: > orig _flags= 602 = 0010 0101 1010 SAVE LOADED READ_LOCKED OID_ASSIGNED > FLUSHED > sm _flags= 16 = 0000 0001 0000 READ_LOCKED > And it is really only 1 instance which makes this problem. If I set the > 'orig' variable to null in the debugger, the test runs fine. -- This message is automatically generated by JIRA.
