addon to 8230613: Better ASCII conversions ?

[Baesken, Matthias]

Hello, recent change

https://hg.openjdk.java.net/jdk/jdk/rev/9e70cd55ae08

8230613: Better ASCII conversions

Adjusted one place  in  file Punycode.java   to throw  the declared 
ParseException in

    public static StringBuffer encode(StringBuffer src, boolean[] caseFlags) 
throws ParseException{  ...  }

I think we should  better adjust  the  remaining  throw   in  the same method  
as well to a ParseException .  See  small patch below.
Should I open a JBS  issue  for this ?

Thanks, Matthias
