New comment by facadeproof on void-packages repository https://github.com/void-linux/void-packages/pull/13208#issuecomment-628194114 Comment: I'm new to building packages with `pkg-src`, but from what I can see in this commit the [libmatthew-unix-java](https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=libmatthew-unix-java) libraries are missing and they are required for sending messages through Java unix sockets. I tried compiling it from source a couple days ago following [this](http://www.matthew.ath.cx/projects/java/) and could build it, for some reason could not get any of the front ends to send messages through `signal-cli`
