java error on linux

[leidner]

Hi all,

I am installing minimServer on Ubuntu server (headless), with Java 9:
openjdk version "9-internal"
OpenJDK Runtime Environment (build 9-internal+0-2016-04-14-195246.buildd.src)
OpenJDK 64-Bit Server VM (build 9-internal+0-2016-04-14-195246.buildd.src, mixed mode)

After entering the music directory, I get this stack trace.

Any ideas how I can fix this?

Thanks!
Marc
