Good afternoon,

Sorry but I have to do it in English.
Yesterday I have installed Fakturama2.
It was working well till this morning.
I get an error when starting up.
I'm running JDK as mentioned below.

OpenJDK Runtime Environment (build 1.8.0_222-8u222-b10-1ubuntu1~18.04.1-b10)
OpenJDK 64-Bit Server VM (build 25.222-b10, mixed mode)

I'm running on Linux Mint 19.2 / 64

The error I get is:

This morning I have added several customers and parts.
Please help me out here.

Thanks, Ron
