Intellij Idea does not start after installation

Hi there,

so, I am trying to run Intellij IDEA Community Edition 2:2017.3.4-1 on Antergos (Arch). Problem: It just doesn't start. I have JDK and JRE 8, JRE 8 headless and JRE 9 headless installed. Log file looks unsuspicious like this:

I read it could help to start IDEA from the command line but I have no idea how to do so und search results always point me to creating a command line launcher from within the program, which is not possible for me because it never started. So... what now?
