[hibernate-dev] Updated JDKs on ci.hibernate.org

[Sanne Grinovero]

Hi all,
I just downloaded these versions of the OpenJDK and replaced the
existing ones on ci.hibernate.org:

jdk-7u80-ea-bin-b05-linux-x64-20_jan_2015.tar.gz
jdk-8u40-ea-bin-b23-linux-x64-27_jan_2015.tar.gz
jdk-9-ea-bin-b49-linux-x64-04_feb_2015.tar.gz

I now triggered several builds of various JDK/project combinations. I
don't expect any regression, but in case there are broken builds,
that's an additional reason to consider.

Thanks,
Sanne
