Bug#875353: FTBFS with Java 9: (mvn) javadoc classpath

[Chris West]

Source: commons-vfs
Version: 2.1
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.
Please fix it, so that we can start the transition to Java 9.
The wiki has some common problems and their solutions:
https://wiki.debian.org/Java/Java9Pitfalls

This fails to find the right classpath during the javadoc build, despite
being a maven project. This is unusual. See the wiki.
