Re: Constructor Instrumentation : super()

I think I am nearing the solution. Yes I can check if
teh INVOKESPECIAL is of some super class. Just have
one more problem now. What if I instantiate the super
class in the constructor by a new statement? How can I
distinguish super() from new(). Both the INVOKESPECIAL
are exactly the same. The only hope now is the DUP
instruction. My assumption is DUP is inserted whenever
new() is used in the code? Am I right? If the answer
is yes, then I can distinguish super() from new().
