Cannot load from short array because "sun.awt.FontConfiguration.head" is null #15

I'm facing this problem when deploying a demo application using the addon using docker:

Caused by: java.lang.NullPointerException: Cannot load from short array because "sun.awt.FontConfiguration.head" is null

        ... 61 more

I suspect that it is related to a missing font in the OS

Fixed with this approach.
