Reflection.getCallerClass(n) does not skip reflection calls in constructors (original) (raw)

Hi

I'm trying to use Reflection.getCallerClass(n) to find out who is calling a method. The method's spec says:

                                  .... Frames associated with
 java.lang.reflect.Method.invoke() and its implementation are
 completely ignored and do not count toward the number of "real"
 frames skipped.

This is very nice but it does not mention Constructor.newInstance(). In fact, I do see the following entries if I'm creating an object thru reflection:

Callee
class sun.reflect.NativeConstructorAccessorImpl
class sun.reflect.NativeConstructorAccessorImpl
class sun.reflect.DelegatingConstructorAccessorImpl
class java.lang.reflect.Constructor
Caller

Is there any reason why we cannot do the same for constructor instantiation?

Thanks Max
