Which version of firmware is installed?

Could you download JRE version 17 from GitHub and check its work on your Paperwhite.

https://github.com/adoptium/temurin1....0.18_8.tar.gz

Extract archive and run jdk-17.0.18+8-jre/bin/java -version

I just created java application for Kindle. Due to limitation of Swing library on Kindle I switched to SWT (Standard Widget Toolkit) library. SWT uses native set of widgets for every system where application run. I use openjre and swt.jar and arm related so libraries (from old debian packages).

Application displays mobileread logo and finishes on tap the screen only.

It is not so much functionality, but it gives ability to run java app on kindle.

I will plan create KUAL extension to convinient way of running.
