Hello,
After release of Wheezy, some really important changes were made to "java-package" which bring improvements and fixes for some of the cardinal problems.
Some of the notable improvements are: Java 8 support, with this version in Wheezy world would be able to build Oracle Java 8 packages.
There's also a better naming scheme:
in Wheezy (0.50+nmu2), after making the jdk/jre packages you would end up with look like:
oracle-j2re1.7_1.7.0+update45_amd64.deb
oracle-j2sdk1.7_1.7.0+update45_amd64.deb
In >=Jessie (0.53) packages you get look like:
oracle-java7-jdk_7u45_amd64.deb
oracle-java7-jre_7u45_amd64.deb
Furthermore, if you build these packages on a >=Jessie machine with 0.53 version, after deploying it on Wheezy machines you'll get unsatisfied dependencies from Jessie. Which makes generated package completely unusable.
Backported package works just fine and doesn't create any dependencies.
Please have it uploaded to backports.
Thanks,
Adnan
