One obvious concern is how long old versions of Java will continue to work. If the deed registry changes their software they can currently produce Java 8 update 201, but will they still be able to produce that release in, say, 2022? Will they be required to purchase a license or change to something other than Java? What if I need to use other software that uses update 211. I'll have to install it, but then switch back to update 201 the next time I need to look up a deed. ...
I use Oracle's Virtual Box to have a Windoze XP computer inside my windoze 10 computer. This allows me to run an old software program in Windoze XP. I just boot up the Virtual Box to use the software, and use the W10 for everything else.
You could set up a similar box for Java 201.
Enjoy
