Package: gtg Version: 0.6-5 Installing gtg pulls out java, which is quite surprizing.
Turns out that pdftk-java is marked as a dependency. According to upstream, this is not intentional and it is not even sure that the features intended to work with the original pdftk still work with pdftk-java https://github.com/getting-things-gnome/gtg/issues/984 pdktk dependency should be marked as "optional" for now
