Bug#873208: FTBFS with Java 9

[Chris West]

Source: dom4j
Version: 1.6.1+dfsg.3-2
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

My build went a bit wrong, dom4j couldn't find org.relaxng. I don't know
what that is. The upstream build also fails, for which I have prepared a
patch:

Cheers,
Chris.
