2nd test of https://datatracker.ietf.org/doc/html/rfc7616#section-3.9 is on
this algorithm, but it requires UTF-8 charset support and a way to provide a
predefined cnonce. If it's not worth modifying our implementation to create a
regression test, I think at least we can temporarily hack our own JDK and try
on it. And I think it's most likely true that this algorithm is using a
different initialization vector as Bernd pointed out.
