> The Java 6 method {{String java.net.IDN.toASCII(String)}} drops the final input character
if it is a dot (or equivalent, see RFC3490 3.1 1)
> This causes problems for authority and domain validation.
> This problem has been seen in 
> Java(TM) SE Runtime Environment (build 1.6.0_65-b14-462-11M4609)
> and
> Java(TM) SE Runtime Environment (build 1.7.0_65-b17)
> but appears to be fixed in
> Java(TM) SE Runtime Environment (build 1.8.0_25-b17)
> Note also that the Java 8 version throws 
> java.lang.IllegalArgumentException: Empty label is not a legal name
> if the argument contains two consecutive dots.
> Fix to follow.
