Accessing most server remote boards requires the browser to support Java, also known as Java Web Start (JWS). Unfortunately Java Web Start has been deprecated starting from Java version 9. Also current Firefox versions do not support Java anymore.

This makes accessing server remote boards increasingly difficult with current browsers. To make life a little easier, and by the help of Docker, we can still use an old Java version supporting Java Web Start together with an old browser version of Firefox to access Java based server remote boards.
