To get -Infinity you have to use -0.0 as the denominator.

My interpretation of your example is as follows:
-0 is done with integer arithmetic, so -0 -> -(0) -> 0 and that gets converted to 0.0 before the division is done. Therefore (+)Infinity is the result.
 
It is sorta covered in the JavaRanch Style Guide.
