Example, but updated

This version is compatible with the recommended release Java 8 Update 401 that currently can be downloaded (the easiest) on the https://www.java.com/ website for end-users.

I've fixed the compatibility issues with Java 8.

Example application

This example provides some sort of "Run"-Dialog (which you might know from Windows) and shows you stdOut and stdErr after running the process. It won't support CLI input applications such as dialog as they're blocking processes but zenity as a GTK+ application (or similar approaches on Microsoft Windows) might work.

To use this application, you should run it using JDK 21. Java 8 tests were not successfull.
