Bug#814173: postgis-java: (Build-)Depends on OpenJDK 7

[Matthias Klose]

Package: src:postgis-java
Version: 1:2.2.0-2
Severity: serious
User: debian-java at lists.debian.org
Usertags: openjdk-8-transition

The package build-depends or depends one an openjdk-7-* package,
which is scheduled for removal for stretch.  Please do not depend
on a specific openjdk version, but on one of the default-java,
default-java-headless or default-jdk packages instead.

default-java defaulting to openjdk-8 on most architectures is now
available in unstable.
