A DESCRIPTION OF THE REQUEST :
When creating a new instance from the Class.newInstance() method, I used a class I had made which didn't have a "nullary" constructor.

At the time I didn't know this would throw an error because I didn't know what a nullary constructor was (I *think* I know what it is - a constructor without any arguments?)

I wasted a fair bit of time looking for other problems.



JUSTIFICATION :
It would have saved a lot of time if the error message was better.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The error message should say: "class being instantiated must have a no-argument constructor" or something to that effect.
