ClassFormatError 0000 6305 on OS400/jdk15
-----------------------------------------

                 Key: JASSIST-38
                 URL: http://jira.jboss.com/jira/browse/JASSIST-38
             Project: Javassist
          Issue Type: Bug
         Environment: OS400/jdk15/jboss-4.2.2.GA/javassist-3.6.GA
            Reporter: Mounir Bakkali
         Assigned To: Shigeru Chiba


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

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!

Sorry to bother you again, but would you have any idea of how to fix this?
(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?
