Bug#874140: FTBFS with Java 9(?): filename encoding

[Chris West]

Source: snakeyaml
Version: 1.17
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 package has a class with intentionally bad encoding in its
filename. I don't know if it's failing to build just on my builder,
or if it's a Java 9 change. But it does fail every time, at least.
