Please refrain from using Math.abs(int) when "non-negative integer" is required

Math.abs(Integer.MIN_VALUE) produces Integer.MIN_VALUE, so Math.abs does not produce "non-negative integers".

return nonNegative != null ? Math.abs(value) : value;

@vlsi Thanks for this. Will adjust.

@vlsi Check out the PR above -- let me know whether or not this will suffice. Thanks!

It looks ok, so people might even learn that the should not try Math.abs(MIN_VALUE) at home :)
