| RE: [aspectj-users] null thisJoinPointStaticPart when advising constructor execution |
|
Here is a
variation on your program that recreates the problem: aspect
Test { public
static void main(String[] argv) { new
C(); } pointcut
methodUnderTestExecution1() : (execution(*
*(..)) || execution(new(..))) && !within(Test); before():
methodUnderTestExecution1() { Object
sig = thisJoinPointStaticPart.getSignature(); // null L System.out.println(sig); } } class B { static
C b = new C(); } class C
extends B { } -----Original
Message----- 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 On 18 March
