Thank you very much Matthias, this is a great news. I'll prepare the
default-jre/jdk packages to default to openjdk-9 and request a mass rebuild.
Regarding the transition here is a good summary of the issues we'll have
to deal with:

I suspect the removal of rt.jar and the merged structure of the JRE/JDK
are going to be the most disruptive changes.
Java 9 is scheduled for release on 22 September 2016 [1]. If Stretch is
frozen exactly 2 years after Jessie in November we might be able to
include it in the next release.
The Java 8 transition is near completion [2], we have only 2 FTBFS left
with no patch available yet (eclipse and lucene-solr, I'm working on
scala, and libjtype-java has a patch ready). There is also an
integration issue (#775775) but it can be solved after switching the
default-jre.
