The problem is that I am defining:

call(javax.microedition.io.*->*(..))

There is an interface javax.microedition.io.Connection in the package. My class is using javax.wireless.messaging.MessageConnection that extends javax.microedition.io.Connection. The code in bold below is being changed by JBossAOP, for javax.wireless.messaging.MessageConnection extends javax.microedition.io.Connection. But the probrem is that resolveCallerMethodInfo can not find the method close() in javax.wireless.messaging.MessageConnection, for close() is declared in javax.microedition.io.Connection. Then the exception is thrown. The method findMethodByHash only tries to find the method in the superclass, but javax.wireless.messaging.MessageConnection is an interface and don't have superclasses. It only extends interfaces (Class.getInterfaces()).

javax.wireless.messaging.MessageConnection conn....
...
...
conn.close();

Thanks,
