Bug#874007: FTBFS with Java 9 due to -source/-target only (weird)

[Chris West]

Source: uima-addons
Version: 2.3.1
Severity: normal
User: debian-java at lists.debian.org
Usertags: default-java9

This package fails to build with default-jdk pointing to openjdk-9-jdk.
The wiki has some common problems and their solutions:
https://wiki.debian.org/Java/Java9Pitfalls

An automated tool has decided that this package will build fine if the
-source and -target options are changed to 1.6; no additional changes
are required. This was done by building with a compiler that changed
the settings automatically, then the real compiler, and diffing the
results. This modified compiler will never be part of Debian.

*** WEIRD ***

This is the only Maven-based package that hits this problem. I didn't
look why.
