However, the tests for Kerberos and DTLS use the KDC server as infrastructure and don't compile because it uses Thread.stop and swallows the UOE. This is tracked by JDK-8360979. It is temporarily changed to use Thread.interrupt to avoid excluding many of tests in these areas.

There should be no conflict as far as I can see, so just noting it here
