Re: [aspectj-users] null thisJoinPointStaticPart when advising construc

[Andy Clement <andrew.clement@xxxxxxxxx>]

Can you tell me what kind of constructors lead to that being null?  A
simple (complete) program that fails would be great.  This program:

---
aspect Test {
  public static void main(String []argv) {
    new C();
  }

 pointcut methodUnderTestExecution1() :
            (execution(* *(..)) || execution(new(..))) && !within(Test);

  before(): methodUnderTestExecution1() {
	  Object sig = thisJoinPointStaticPart.getSignature();
      System.out.println(sig);
  }

}

class C { }
---

works fine and prints C().

cheers
Andy
