Hi, I found a thread on the list (http://archives.apache.org/eyebrowse/[EMAIL PROTECTED] he.org&msgId=593039) in which it is said: >Indeed you stumbled across a bug in the ObjectEnvelopeTable class. The >bug was fixed on 2002/12/23 13:27:59 which means it is not available on >version 0.9.8. It is however available directly from the cvs server. > >The Concurrent Modification Exception occurs while upgrading the >locks in a commit operation of the ObjectEnvelopeTable class. The >solution we came up with was to iterate over temporary vector while >upgrading the locks. > >Cheers, >Luis Cruz I have just downloaded the latest cvs version, and I have the same problem. Did the change get lost by any chance? --Bill My stack trace: [java] java.util.ConcurrentModificationException [java] at java.util.AbstractList$Itr.checkForComodification(AbstractList.java:444) [java] [org.apache.ojb.odmg.ObjectEnvelopeTable] ERROR: Commit on object level failed for tx [EMAIL PROTECTED] [java] at java.util.AbstractList$Itr.next(AbstractList.java:417) [java] at org.apache.ojb.odmg.ObjectEnvelopeTable.commitAllEnvelopes(ObjectEnvelopeTab le.java:218) [java] at org.apache.ojb.odmg.ObjectEnvelopeTable.commit(ObjectEnvelopeTable.java:187) [java] null [java] [org.apache.ojb.odmg.TransactionImpl] ERROR: Could not prepare for commit: null [java] at org.apache.ojb.odmg.TransactionImpl.doCommitOnObjects(TransactionImpl.java:3 26) [java] at org.apache.ojb.odmg.TransactionImpl.prepare(TransactionImpl.java:575) [java] at org.apache.ojb.odmg.TransactionImpl.commit(TransactionImpl.java:525) [java] at test.Test.main(Test.java:70) [java] [org.apache.ojb.broker.accesslayer.ConnectionManagerImpl] INFO: Rollback was called, do rollback on current connection [EMAIL PROTECTED] [java] java.sql.SQLException: General error: Warning: Some non-transactional changed tables couldn't be rolled back [java] at org.gjt.mm.mysql.MysqlIO.sendCommand(MysqlIO.java:497) [java] [org.apache.ojb.broker.accesslayer.ConnectionManagerImpl] ERROR: Rollback on the underlying connection failed [java] at org.gjt.mm.mysql.MysqlIO.sqlQueryDirect(MysqlIO.java:550) [java] at org.gjt.mm.mysql.MysqlIO.sqlQuery(MysqlIO.java:635) [java] General error: Warning: Some non-transactional changed tables couldn't be rolled back [java] at org.gjt.mm.mysql.Connection.execSQL(Connection.java:882) [java] at org.gjt.mm.mysql.Connection.execSQL(Connection.java:815) [java] at org.gjt.mm.mysql.Connection.rollback(Connection.java:551) [java] at com.p6spy.engine.logging.P6LogConnection.rollback(P6LogConnection.java:145) [java] at org.apache.ojb.broker.accesslayer.ConnectionManagerImpl.localRollback(Connec tionManagerImpl.java:245) [java] at org.apache.ojb.broker.singlevm.PersistenceBrokerImpl.abortTransaction(Persis tenceBrokerImpl.java:358) [java] at org.apache.ojb.broker.singlevm.PersistenceBrokerImpl.close(PersistenceBroker Impl.java:320) [java] at org.apache.ojb.broker.singlevm.DelegatingPersistenceBroker.close(DelegatingP ersistenceBroker.java:132) [java] at org.apache.ojb.broker.singlevm.PoolablePersistenceBroker.close(PoolablePersi stenceBroker.java:28) [java] at org.apache.ojb.odmg.TransactionImpl.doClose(TransactionImpl.java:424) [java] at org.apache.ojb.odmg.TransactionImpl.commit(TransactionImpl.java:548) [java] at test.Test.main(Test.java:70) [java] org.odmg.TransactionAbortedException [java] at org.apache.ojb.odmg.ObjectEnvelopeTable.commit(ObjectEnvelopeTable.java:198) [java] at org.apache.ojb.odmg.TransactionImpl.doCommitOnObjects(TransactionImpl.java:3 26) [java] at org.apache.ojb.odmg.TransactionImpl.prepare(TransactionImpl.java:575) [java] at org.apache.ojb.odmg.TransactionImpl.commit(TransactionImpl.java:525) [java] at test.Test.main(Test.java:70) [java] Exception in thread "main" [java] Java Result: 1
