Development of Open Eggbert

Multiplatform

Open Eggbert is multiplatform (desktop, Android, web).

We should assure continuously, that the latest version (snapshot) runs correctly on all the 3 supported platforms.

This means some limitations: Only feature of Java 11 source code level are supported, but even some Java 11 features are not supported in GWT.

Method String.lines(String string) is not present in GWT.
- How to fix: Use method OpenEggbertUtils.lines(String string)
Method Stream.toList() is not present in GWT
- How to fix: Use Stream.collect(Collectors.toList())
