Description Eduardo Francos CLA 2007-02-09 03:19:33 EST 
The following exception is caused by a duplicate inter-type introduction method declaration in an aspect. Removing the duplicate method solves the problem.

java.lang.NullPointerException

NullPointerException thrown: null
Comment 1 Andrew Clement CLA 2008-03-19 01:16:57 EDT 
Still failing in 1.6 - this code:

public aspect X {
  public void Y.foo(String s) {}
  public void Y.foo(String s) {}
}

class Y {}
 

gives

java.lang.NullPointerException
