Description:
I Installed the unifi package (Version 3.2.5-1)

I started the service with systemctl start unifi. After a couple of seconds the service died. After looking through the journal I discovered that java needed a shared lib (cups) which was not installed on my system and not requested during the installation of the unifi package.

the installation of cups (and its dependencies) resolved the error and the unifi controller started as expected.

Additional info:
* 3.2.5-1
* Oct 29 11:09:32 hostname java[9591]: Caused by: java.lang.UnsatisfiedLinkError: /usr/lib/jvm/java-7-openjdk/jre/lib/amd64/headless/libmawt.so: libcups.so.2: cannot open shared object file: No such f

Steps to reproduce:
Install unifi package (3.2.5-1) (pacman -S unifi) on a system where cups is not installed
start unifi (systemctl start unifi)
check logs after a couple of seconds (journalctl -> scroll to end)
This task depends upon

I can reproduce this if I uninstall "libcups" on my system.

I see a lot of issues on the web about this (on Arch Linux and others and for different Java apps):

Also it seems IcedTea project (which we use to build our OpenJDK7) is aware of the strong dependency on libcups:

So I would be in favor of adding "libcups" as a makedepends and depends for jre7-openjdk-headless.

I agree.

Guillaume, I see you forget to update libcups deps in last testing version of jre7-openjdk-headless.

My bad. Forgot it as pushing to testing was not planned. Rebuilding right now. Thanks for the reminder.
