I'm pretty sure, yes.  The "new" operator always has to return an 
object, or throw an error.  Factory methods are just methods, and can 
return null, but new *must* return an object if it completes.

P.S. Don't use assertTrue just to print something.  Just use 
System.out.println, it works fine, and makes your intent more clear.
