RuntimeUtils.msg(...) argument validation logic might be faulty

[Marcono1234]

It appears the argument validation logic in RuntimeUtils.msg(...) might be faulty:

Java-Objective-C-Bridge/src/main/java/ca/weblite/objc/RuntimeUtils.java

Lines 587 to 589 in 473221a

	if ( numArgs ==2 && numArgs != args.length+2 ){
	throw new RuntimeException("Wrong argument count. The selector "+selName(selector)+" requires "+(numArgs-2)+" arguments, but received "+args.length);
	}

I am not really familiar with this project, but I assume it should check for numArgs >= 2 (instead of == 2)?
Otherwise the calculation numArgs-2 in the error message is redundant because it would always be 0.

It might also be good to throw a more specific exception, e.g. IllegalArgumentException.
(Same for the other methods throwing RuntimeException when illegal arguments are provided)
