Cannot get working on Kubuntu 18.04

I have a pretty standard Linux Kubuntu 18.04 installation.
I did set up Serviio according to viewtopic.php?f=6&t=24883

My java :

  Code:

java --version
openjdk 10.0.2 2018-07-17
OpenJDK Runtime Environment (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.4)
OpenJDK 64-Bit Server VM (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.4, mixed mode)

All *seems* to go correct, I can start server, add folders that are picked up etc. But nothing is presented to my DLNA clients.

It might be related to following that I find in the syslog :

  Code:

Feb  2 14:32:47 xx serviio.sh[27822]: Could not invoke DirectBuffer method - illegal access
Feb  2 14:33:16 xx  serviio.sh[27822]: message repeated 226 times: [ Could not invoke DirectBuffer method - illegal access]


Any idea if there is a relation or how I can get Serviio working ?

Follow-up from myself ...

Probably the real issue is rather this I find in the log files. No clue though how to address ...

  Code:

Further followup :

It seems I bumped into viewtopic.php?f=5&t=24926

The Kubuntu 18.04 standard installed java is not OK.
Installed openjdk-8 and patched serviio.sh with `JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/jre`

And we're all good again
