Alex's approach is good, and is modeled after the similar treatment in datetime classes.

There's the somewhat related issue that 

>>> import math
>>> math.fabs
<java function fabs 0x2>

instead of CPython 2.7

>>> import math
>>> math.fabs
<built-in function fabs>

is what the math function is, which is what caused us to go with __tojava__ to begin with, which confused my thinking about this bug, but that's a larger problem.

Fixed as of https://hg.python.org/jython/rev/d86bf9da41c7
