Issue2159

The function sqrt from the math-module throws a "math domain error" for the argument "-1" but not for other negative values such as "-2". It should raise a "math domain error" for all negative arguments.

The "sqrt" function in math.java (Jython 2.7) should be changed to (note the "v < ZERO" instead of "v == MINUS_ONE"):

    public static double sqrt(double v) {
        if (isnan(v)) {
            return v;
        }
        if (ispinf(v)) {
            return v;
        }
        if (isninf(v) || v < ZERO) {
            throwMathDomainValueError();
        }
        return Math.sqrt(v);
    }

This has already been addressed in this commit: https://bitbucket.org/jython/jython/diff/src/org/python/modules/math.java?diff2=a5b000944a51&at=default
