Ah, I see your message from 2012-11-26 05:46.

And Class.newInstance. Which gives a clue to a problem. Any code that is 
using Constructor.newInstance has to be as careful with it as they are 
with Method.invoke. Slightly more so, as constructors lean on 
overloading rather than having names like all self-respecting methods. 
As we know from experience, existing code does automatically take into 
account bizarre new requirements. I think we have a sufficient quantity 
of caller-sensitive stuff without taking it into new directions.

(From reading the HotSpot sources some time ago (may have changed), in 
particular circumstances some, but not all, constructor reflection 
frames may disappear.)
