Bug#875594: FTBFS with Java 9: test failures around reflection on core classes

[Chris West]

Source: kryo-serializers
Version: 0.22-3
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

It goes digging around in core classes and looking at their fields. This
will be banned in a future release. I can't see where it's doing it in
the code at the moment, but I suspect it has some implementation details
of e.g. ArrayList hardcoded.

This package has no rdeps, and is a library, so could be RM'd. It was
added as a build-dep of sbt, which might be coming back into Debian at
some point, so maybe people will argue to leave it for that reason.
