Re: [aspectwerkz-dev] stack overflow in cvs head

hey

i have now isolated the problem further, and found a really easy way to
reproduce it:

this class:


public class Guess  {

     public Guess(Guess no) {
     }

     static public void main(String[] args) {
     }
}

also produces a stacktrace when its preprocessed.
so i think that the preprocessor fails if a class has no default
constructor.


regards
  chris
