[ http://jira.jboss.com/jira/browse/JASSIST-38?page=all ] Mounir Bakkali updated JASSIST-38: ---------------------------------- Description: I have been using JBoss Seam framework and when using it on OS/400 (i-series/IBM) with jdk15, javassist generates an exception: Caused by: javassist.CannotCompileException: by java.lang.ClassFormatError: <mypkg>/SubCategoryRevision_$$_javassist_0 0000 6305 at java.lang.Throwable.<init>(Throwable.java:196) at java.lang.Exception.<init>(Exception.java:41) at javassist.CannotCompileException.<init>(CannotCompileException.java:73) at javassist.util.proxy.FactoryHelper.toClass(FactoryHelper.java:125) at javassist.util.proxy.ProxyFactory.createClass(ProxyFactory.java:169) ... 48 more Caused by: java.lang.ClassFormatError: <mypkg>/SubCategoryRevision_$$_javassist_0 0000 6305 at java.lang.Throwable.<init>(Throwable.java:196) at java.lang.Error.<init>(Error.java:49) at java.lang.LinkageError.<init>(LinkageError.java:36) at java.lang.ClassFormatError.<init>(ClassFormatError.java:35) at java.lang.ClassLoader.defineClass(ClassLoader.java:651) at java.lang.ClassLoader.defineClass(ClassLoader.java:496) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at javassist.util.proxy.FactoryHelper.toClass(FactoryHelper.java:117) Also, when I use cglib everything works so I assume this is a javassist issue. When I use Hibernate alone(no Seam), it also gives me the exact same exception but when I change the configuration to force Hibernate to use cglib, everything works fine again. Also any Seam-2.0.0.GA example will generate the same exception! I would like to use JBoss Seam but at some point the Seam framework uses javassist. This problem only occurs when I use the OS400 jdk15. When I use the Sun jdk on my PC it all works very well. Any idea of how to solve this issue? was: I have been using JBoss Seam framework and when using it on OS/400 (i-series/IBM) with jdk15, javassist generates an exception: Caused by: javassist.CannotCompileException: by java.lang.ClassFormatError: <mypkg>/SubCategoryRevision_$$_javassist_0 0000 6305 at java.lang.Throwable.<init>(Throwable.java:196) at java.lang.Exception.<init>(Exception.java:41) at javassist.CannotCompileException.<init>(CannotCompileException.java:73) at javassist.util.proxy.FactoryHelper.toClass(FactoryHelper.java:125) at javassist.util.proxy.ProxyFactory.createClass(ProxyFactory.java:169) ... 48 more Caused by: java.lang.ClassFormatError: <mypkg>/SubCategoryRevision_$$_javassist_0 0000 6305 at java.lang.Throwable.<init>(Throwable.java:196) at java.lang.Error.<init>(Error.java:49) at java.lang.LinkageError.<init>(LinkageError.java:36) at java.lang.ClassFormatError.<init>(ClassFormatError.java:35) at java.lang.ClassLoader.defineClass(ClassLoader.java:651) at java.lang.ClassLoader.defineClass(ClassLoader.java:496) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at javassist.util.proxy.FactoryHelper.toClass(FactoryHelper.java:117) Also, when I use cglib everything works so I assume this is a javassist issue.
