[System] Check for null add empty only condition

[wangkanai]

The check for null is now getting more complicated with each new edge case during my investigative journey. I find that we should have checking just for empty string. Also adding to this, an ArgumentEmptyException to go along with the check.

Then come the point of the instance activator of creating exception instance when the condition is found to be throw.

I feel now that the Check is getting very organized, but in the meantime, the class is gaining lines of code up to 500. if this trend continues on this path. I will need to consider refactor them into more manageable smaller class.
