javassist.bytecode.DuplicateMemberException: for loadtime instrumentation of classes loaded by hibernate. --------------------------------------------------------------------------------------------------------- Key: JBAOP-549 URL: http://jira.jboss.com/jira/browse/JBAOP-549 Project: JBoss AOP Issue Type: Bug Security Level: Public(Everyone can see) Environment: Windows OS, JDK 5.x , hibernate as ORM Reporter: Bahata Mukhopadhyay Hi I am getting the following exceptions , when trying to use loadtime instrumentation of my dao objects which are getting loaded using hibernate. The exception occurs both in Habanero and Alegrias . I need to use Jboss Pojo cache in fron of hibermnate, not as second level cache. Please help. (Also note that , I was trying to use AOPC to do compile time instrumentation. It had no problem. But as we have FAT/SMART clients in our application, and need to transfer serialized copies of the POJOs stored in cache, I was having a problem as the classes weaved with AOPC were having the class-interceptors as their field. So I was getting a Not-Serializable exception . I wanted to check with load time instrumentation to avoid that problem) javassist.bytecode.DuplicateMemberException: duplicate method: _getAdvisor in ft.oots.adt.dao.Alert$$EnhancerByCGLIB$$c2fd0509 at javassist.bytecode.ClassFile.testExistingMethod(ClassFile.java:559) at javassist.bytecode.ClassFile.addMethod(ClassFile.java:539) at javassist.CtClassType.addMethod(CtClassType.java:1170) at org.jboss.aop.instrument.ClassicInstrumentor.addHelperClass(ClassicInstrumentor.java:187) at org.jboss.aop.instrument.ClassicInstrumentor.doSetupBasics(ClassicInstrumentor.java:157) at org.jboss.aop.instrument.Instrumentor.setupBasics(Instrumentor.java:887) at org.jboss.aop.instrument.Instrumentor.instrumentIntroductions(Instrumentor.java:366) at org.jboss.aop.instrument.Instrumentor.transform(Instrumentor.java:717) at org.jboss.aop.AspectManager.translate(AspectManager.java:909) at org.jboss.aop.AspectManager.transform(AspectManager.java:821) at org.jboss.aop.standalone.AOPTransformer.aspectTransform(AOPTransformer.java:88) at org.jboss.aop.standalone.AOPTransformer.transform(AOPTransformer.java:75) at sun.instrument.TransformerManager.transform(TransformerManager.java:122) at sun.instrument.InstrumentationImpl.transform(InstrumentationImpl.java:155) at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:620) at sun.reflect.GeneratedMethodAccessor36.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at net.sf.cglib.core.ReflectUtils.defineClass(ReflectUtils.java:384) at net.sf.cglib.core.AbstractClassGenerator.create(AbstractClassGenerator.java:219) at net.sf.cglib.proxy.Enhancer.createHelper(Enhancer.java:377) at net.sf.cglib.proxy.Enhancer.createClass(Enhancer.java:317) at org.hibernate.proxy.CGLIBLazyInitializer.getProxyFactory(CGLIBLazyInitializer.java:126) at org.hibernate.proxy.CGLIBProxyFactory.postInstantiate(CGLIBProxyFactory.java:41) at org.hibernate.tuple.PojoEntityTuplizer.buildProxyFactory(PojoEntityTuplizer.java:161) at org.hibernate.tuple.AbstractEntityTuplizer.<init>(AbstractEntityTuplizer.java:131) at org.hibernate.tuple.PojoEntityTuplizer.<init>(PojoEntityTuplizer.java:55) at org.hibernate.tuple.TuplizerLookup.create(TuplizerLookup.java:64) at org.hibernate.tuple.EntityMetamodel.<init>(EntityMetamodel.java:257) at org.hibernate.persister.entity.AbstractEntityPersister.<init>(AbstractEntityPersister.java:412) at org.hibernate.persister.entity.SingleTableEntityPersister.<init>(SingleTableEntityPersister.java:108) at org.hibernate.persister.PersisterFactory.createClassPersister(PersisterFactory.java:55) at org.hibernate.impl.SessionFactoryImpl.<init>(SessionFactoryImpl.java:216) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1176) at ft.hibernate.HibernateUtil.<clinit>(HibernateUtil.java:18) at ft.oots.controller.DatabaseController.getUser(DatabaseController.java:867) at ft.oots.controller.DatabaseController.verifyUser(DatabaseController.java:398) at ft.oots.controller.LoginController.verifyUser(LoginController.java:73) at ft.oots.controller.ServerController.validateUser(ServerController.java:204) at ft.oots.controller.LoginController.showLoginScreen(LoginController.java:58) at ft.oots.Application.showLoginScreen(Application.java:178) at ft.oots.Application.<init>(Application.java:120) at ft.oots.Application.main(Application.java:522)
