Hi,
Seeing 'debug weaving' but no 'weaveinfo' suggests your pointcuts just
don't match.
Actually, if I go back to your pointcut it says:
within(com.example.*) && call(* *(..));
Which means 'any call made from inside com.example.*'. Because you
used .* and not ..* it will not be including subpackages of
com.example.<anything> - I hope that is what you intended to do? As
you mentioned it was doing what you expect on the command line, I
assumed the pointcuts were OK. Maybe try something even more simple
to check the mechanism is ok? something like
before(): staticinitialization(*) {
System.out.println("staticinitialization"); }
