Weird VerifyError on deploy

[bmacy]

I have an MBean that calls a function on a Stateless Session Bean. If I redeploy the EJBs (which the Stateless Session Bean is part of) I get a VerifyError exception:

14:22:15,039 ERROR [EJBDeployer] Verfiy failed
java.lang.VerifyError: (class: com/pany/session/AlertEngineBean, method: getNextAlertProcessor signature: ()Lcom/pany/interfaces/Processor;) Incompatible object argument for function call

This particular function takes no arguements and returns a Processor object (which despite the class path is an abstract base class and not an interface). Processor is not an EJB but is serializable.

Anyways, I don't know why this error would occur. This in on 3.0.0 or 3.0.1rc1 (which 3.0.1rc1 got rid of the Circularity and other weird problems I was having with stock 3.0.0).

And for the full stacktrace (note this deploy is done by touching the existing jar file):

14:45:44,465 ERROR [EJBDeployer] Verfiy failed
java.lang.VerifyError: (class: com/pany/session/AlertEngineBean, method: getNextAlertProcessor signature: ()Lcom/pany/interfaces/Processor;) Incompatible object argument for function call
