Re: Code review request, 8020842 IDN do not throw IAE when hostname ends with a trailing dot

[Weijun Wang]

   if (q < input.length()) {   // Ah, a dot!
     out.append('.');
   }
   p = q + 1;

Using

  if (q != input.length())

should be even better. The searchDots method clearly specifies that "or 
if there is no dots, return the length of input string".
