Lookup the method caller inside the called method

Supose that we have this stackTrace

ViewField.getValue()
ExpressionEl.doSomethink()
....
HtmlInput.getValue()

Is it possible to get the instance of the HtmlInput whose calling thoses methods inside the ViewField.getValue() ?

Unfortunatly the stacktrace didn't contain the reference of the caling objects, so how to do it?

One method that is kinda ugly but will definitely work is manually passing the reference to each method call.

If you had a method

void foo(String a,int b,...)

now it would be 

void foo(String a,int b,Object c,...)

and then everywhere you call it just pass a reference to this.
