>>From this code fragment:

class Confuse {

        public static void main (String[] bob) 
        {
                boolean jim;

                jim=wtf(true);
                System.out.print("Calling wtf(true):");
                System.out.println(jim);

                jim=wtf(false);
                System.out.print("Calling wtf(false):");
                System.out.println(jim);
        }

        static boolean wtf(boolean jam) {
                while (jam)
                {
                        try {
                                return true;
                        }
                        finally {
                                break;
                        }
                }
                return false;
        }
}

As you can see the compile to class files seems to be wrong, and further the
compiler and not the VM.
