openjdk-9 available in experimental

[Matthias Klose <doko@debian.org>]

Hi,

openjdk-9 is now available in experimental.  for now it just builds on amd64 and
i386.  However I'd like to evaluate if we can skip openjdk-8 for stretch and
default to openjdk-9 (the road map would still be to default to openjdk-8 first,
and then to -9).  Is there anybody who wants to volunteer for a test rebuild of
all java packages with openjdk-9?  Compared to openjdk-8, openjdk-9 provides
hotspot vm's upstream for more release architectures than openjdk-8 would do.
However, this is an early build, not near a feature freeze openjdk-9 upstream.
