All of these calls
  math.sqrt(negative value)
  math.log(negative value)
should raise
  ValueError: math domain error

Current jython 2.7 just returns NaN or Inf.

Attached is a bugtest script.

Fix and test.

This fix still seems to be buggy:

Python 2.7:
>>> math.sqrt(-0.5)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: math domain error

>>> math.sqrt(-0.5)
