Bug#775987: maven: Maven depends on openjdk exclusively

[Emmanuel Bourg]

Hi Laurens,

Thank you for the report. I think this is actually an issue with
java-package. The package generated by make-jpkg provides
java<n>-runtime[-headless] with n covering the last 3 versions. So for
Java 8 it provides java{6,7,8}-runtime but not java5-runtime as required
by maven.

We should modify make-jpkg and provide all runtimes since Java 5.
