Beta: Java 8 for AmigaOS 4 (PowerPC) - JamVM 2.0 + OpenJDK 8 on clib4, with a native AWT/Swing toolkit.

Java-OS4 stands on a great deal of prior work, with gratitude:

JAmiga by jaokim — the Java-on-Amiga effort this project revives and extends. The AmigaOS 4 JamVM port and the IcedTea 8 build harness are the foundation we built on.

First beta release of Java-OS4 — a Java 8 runtime for AmigaOS 4 (PowerPC): JamVM 2.0 + the OpenJDK 8 class library on clib4, with a native AWT/Swing toolkit so Java GUIs run in Workbench windows.

What works
Headless Java 8 programs — collections, streams/lambdas, NIO, reflection, serialization, zip, text.
Swing/AWT GUIs in Intuition windows: real mouse and keyboard input, window resize, modal dialogs, fonts via FreeType.
Zero-flag GUI launch: java -cp app.jar Main starts a Swing app with no special options.

Sounds interesting for sure !

It said "Java GUIs run in Workbench windows" , it mean not proper integration with menus and co, but main intution window in which all "alien" interface are ? Just like it was with firefox/timberwolf ?

Anyway, is there anything which were tested and worked which can show how it all ? I mean, not simple test cases, but something which using swing/awt so we can have see how it acts now on os4 ?

Thanks!

Its the continuation of the old work of Jaokim or its a new fresh implementation?

Im adding things as I go, however its really just a stepping stone towards OpenJDK 17 LTS support.

@derfs
Tested briefly:

- you added Assign >NIL: JAVA: "path:Java/" , to user-startup, but didn't mention user need to reboot before he can run "java" binary.
- also, with this one assign you can't run "java" bin from anywhere, you need to run it like "java:java -version", because pure "java" will not find it, as JAVA: assing isnt' added as system one.
- "java" file is script, but not marked as executable. Probably you pack archive wrong or forget about bit set (or copy it from pc where it looses). protect +es fixed it.

Didn't find any working test examples in archive, but so far it seems to runs, and -version working.

isn't that just a matter of running it once with the path, and then it will be in APPDIR:, which by default is in the system path?
