Recently I wanted to see if some code I wrote still worked on Java 1.x.

The only way I could get Java 1.x to run (among my fleet of existing machines) was by installing the windows JDK version to run inside Wine on my Ubuntu.

Native Windows 10 could not run Java 1.x. This surprised me, since in my previous experience Windows was pretty amazing for maintaining reverse compatibility.

(I guess I could grab a super-old Debian docker image like Debian 6 and see if the linux Java 1.x binary would run on that, but I wanted to stick with machines I already had running.)
