No objections :-) I think it’s a better location to find such methods. Moved, and i also tweaked to class doc of Objects to include static methods for “checking certain conditions before operation”.

I clarified the exception constructors that access one to two out of band values to say they are included in the exception detail message (without actually specifying the presentation format of that message).
