AroundInvokeAnnotationParsingProcessor should fail when more methods with @AroundInvoke annotation is found in the class.
The specification says:

A class must not declare more than one AroundInvoke method.

The JBoss AS allows more such methods and then it chooses one of them which is used as the interceptor.

It becomes even more important to check the interceptor validity now with the new feature introduced by AS7-5897 (server side non-EE interceptors for EE invocations).
