In my experience, most of the more important Java-on-the-web stuff was Java Web Start as opposed to applets. And Java Web Start was all kinds of bad. About the only remotely good thing I could say is that it has a sandbox. Which protected no one from anything, by design, because it was the app’s choice whether to use it. And Web Start apps also often included native code, too, so they weren’t even portable.

So much JWS PTSD. Industrial automation got a giant dose of it and those things somehow weren’t even portable to different versions of internet explorer.
