[Debian-med-packaging] Bug#875789: Bug#875789: FTBFS with Java 9: tests error out

[Olivier Sallou]

I had a quick look.

I made some modifications for Java 9 , but the tests do not match usual
Java 9 migration issues and tests do not show any special problem, only
NullPointerException

    <error
type="java.lang.NullPointerException">java.lang.NullPointerException

I have no idea why, but this is not a simple Java9 migration.

So I have not pushed my updates yet as this is not the current problem.
