if you take a look at
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/instrument/Instrumentation.html
you'll notice redefineClasses(ClassDefinition[]) method that looks 
promising. Unfortunately as of Sun JDK 1.5.0 it cannot add, remove or 
change signature of methods nor modify inheritance, so it is not 
sufficient for the kind of class modifications AJ performs. Maybe in 
future releases...
