Dear group,
I just started to try using OpenEJB for testing my EJB beans. So, I'm
pretty beginner with OpenEJB (and OpenJPA).
I hit the next exception (what I cannot overcome) in my test using
OpenEJB's ApplicationComposer:
Exception stacktrace:
Caused by: java.rmi.RemoteException: The bean encountered a non-application
exception; nested exception is:
<openjpa-2.2.0-r422266:1244990 fatal general error>

}
I traced and dumped the calls from ClassRedefiner.redefineClasses to
reflect.Method.invoke:

It's puzzling me why sun.instrument.InstrumentationImpl.retransformClasses
method throws the VerifyError exception, since, from the above dump, it
appeared to me that the array local field in the
ClassRedefiner.redefineClasses method holds the array of the proper entity
bean classes.
Environment:
OpenEJB ver 4.5.2
OpenJPA ver 2.2.0 (as resolved openjpa-asm-shaded dependency from
openejb-core artifact dependency)
EJB 3
JDK 1.7.0
Windows box
Can someone shed the guiding light?
I appreciate any advises since I am pretty beginner of OpenEJB (and
OpenJPA).
Regards,
Art
