have proxy from ThreadLocalCurrentSession better handle UndeclaredThrowableException ------------------------------------------------------------------------------------ Key: HHH-1032 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1032 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.1 rc 1 Environment: win2k, db2 Reporter: Barthel Steckemetz Priority: Trivial Original Estimate: 1h Remaining Estimate: 1h In previous version of hibernate saving two object with the same id gave an NonUniqueObjectException which could easily be caught as it is derived from HibernateException. However in Hibernate 3.1 rc1 I get this stacktrace: java.lang.reflect.UndeclaredThrowableException at $Proxy0.save(Unknown Source) at de.ifbfag.base.db.HSession.save(HSession.java:230) at com.ifbag.okular.base.hibernate.tst.HibInteractive.lifecycleMitExceptions(HibInteractive.java:195) at com.ifbag.okular.base.hibernate.tst.HibInteractive.start(HibInteractive.java:56) at com.ifbag.okular.base.hibernate.tst.HibInteractive.main(HibInteractive.java:41) Caused by: java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.hibernate.context.ThreadLocalSessionContext$TransactionProtectionWrapper.invoke(ThreadLocalSessionContext.java:266) ... 5 more Caused by: org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session: [com.ifbag.okular.base.hibernate.tst.User#ifb0] at org.hibernate.event.def.AbstractSaveEventListener.performSave(AbstractSaveEventListener.java:154) at org.hibernate.event.def.AbstractSaveEventListener.saveWithGeneratedId(AbstractSaveEventListener.java:114) at org.hibernate.event.def.DefaultSaveOrUpdateEventListener.saveWithGeneratedOrRequestedId(DefaultSaveOrUpdateEventListener.java:186) at org.hibernate.event.def.DefaultSaveEventListener.saveWithGeneratedOrRequestedId(DefaultSaveEventListener.java:33) at org.hibernate.event.def.DefaultSaveOrUpdateEventListener.entityIsTransient(DefaultSaveOrUpdateEventListener.java:175) at org.hibernate.event.def.DefaultSaveEventListener.performSaveOrUpdate(DefaultSaveEventListener.java:27) at org.hibernate.event.def.DefaultSaveOrUpdateEventListener.onSaveOrUpdate(DefaultSaveOrUpdateEventListener.java:70) at org.hibernate.impl.SessionImpl.fireSave(SessionImpl.java:523) at org.hibernate.impl.SessionImpl.save(SessionImpl.java:513) at org.hibernate.impl.SessionImpl.save(SessionImpl.java:509) ... 10 more where the original exception is contain in a rather ugly UndeclaredThrowableException.
