Hi Alan, I do not have such a test case .
Is there one for the  change 8230613 ?

The only call to Punycode.encode in IDN.java  is  below and the coding intends 
to catch java.text.ParseException  from  Punycode.encode
and then throws an IllegalArgumentException . I see nothing  regarding  
RuntimeException  in IDN .

Tests for changes in security updates are not included in the jdk repo.

IDN.toASCII only specifies IAE so it would be useful to find input that tickles other (non-resource) exceptions. Aleksei tells me that he couldn't find input that would cause this so this is why it was not changed at the time.
