Bug#875580: FTBFS with Java 9: -source, enum as keyword

[Chris West]

Source: jcharts
Version: 0.7.5
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:

-source is set to 1.5, which is too low. After fixing this, 'enum' is
used as a keyword, which is now illegal.

Build log:
