Bug#875329: FTBFS with Java 9: _ as identifier

[Chris West]

Source: akuma
Version: 1.10-1
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

_ is not a valid identifier any longer.
Upstream issue, currently ignored:
