Getting the java version to work was quite a journey...
The final working command:
appletviewer applet.html
Where
hack $ cat applet.html <applet code="M" width="500" height="500"></applet>
And the M.class is in the directory.
Along the way, I:
- installed a java decompiler https://github.com/fesh0r/fernflower after http://www.javadecompilers.com/ wanted me to turn off my ad blocker
- installed java 8 in 2 ways, from java.com and from homebrew
- learned how to use the built-in macos tar to extract a rar file
tar -xvf Minecraft 4k.rar
- learned how to use /usr/libexec/java_home to find the location of Java 1.8
- recompiled the decompiled version but got an error because the new class file wasn't compatible with old jre
- learned how to use the java debugger (from appletviewer)
hack $ appletviewer -debug M.class Initializing jdb ... > run run sun.applet.Main M.class Set uncaught java.lang.Throwable Set deferred uncaught java.lang.Throwable > VM Started: The application exited
Feels like retro computing... code that should be in a museum ... something like that.
