I'm not sure I understand exactly, but as the comment says,
always make your error-checking code look like this:
*
* if (guardExpression) {
* throw new BadException(badMsg(...));
* }
*
although in String it's not so important because
there's no String concatenation, which is a notable cause
of cold bytecode bloat.
