Oracle itself still sells and supports software that runs client-side as Java applets in IE (the "server" that comes with it is an old HP desktop).
If you ever peek at the software some industries are running, you may find yourself extremely surprised. A lot of it is incredibly specific, and truly terrible.
Some applets could be launched with javaws, but it would require some tinkering to extract proper jnlp file from HTML or JavaScript. I managed to do so with HP iLO remote KVM app.

For me, it's a yes. My employer uses some ancient monitoring application called SiteScope. They recently "upgraded" from an ancient version to a newer one (I think the latest), and nearly the whole frontend appears to be implemented as a Java Applet. Since no browser on the Mac supports Applets anymore, their workaround was to download some Java App that ran the UI.
> I love the concept that the solution is to work around the applet issue and not find some new monitoring software.
The workaround is actually part of the software itself (there are instructions right below the login box).
My understanding is they're only upgrading because the old version didn't support modern versions of TLS, and there's a big push to get off of those. Finding new monitoring software would be probably be more work. At a minimum, the new version probably supports all the features we're using, and at best all our configuration can be automatically migrated. I don't know the details: I'm not part of the project, I just have an some apps with some monitors setup for them.
