It would be very nice to allow calling super.method() in an ITD, where the super implementation is itself and ITD. Unfortunately, I don't think it's possible with the current Java bytecode definition. Failing that, the compiler should be consistent and flag an error. Here's the output from a program that compiles then fails at runtime (both with 1.5.0 and the Mar. 28 nightly build):

java pkg.Derived
Exception in thread "main" java.lang.AbstractMethodError: pkg.Derived$1.ajc$supe
