Flow analysis catches the bug early (at compile time): the 
default value of null is not what you want in most cases, and you 
don't want null to leak into your system and cause a crash at 
unknown time, unknown place, whether it will be deterministic is 
another question. In .net the problem is worse because strings 
are classes there and calling member methods on a null string 
causes NullPointerException.
