My desktop running 10.11.6 and my just-updated laptop running 10.12 do not have any of the old files. However, my friend, whom I am confident has upgraded to 10.12, shows the old files still in his /System/Library/Java/Extensions directory. All files are dated Jul 6 2015.

On my systems, I had run an app (provided to my users) that moved the troublesome files to a ./hold_j3d subdirectory off of the above, and to be a good citizen, there was also an app that undid the move. I suppose that the directory might have gotten deleted during subsequent upgrades, while my friend's upgrades retained all of the files in the original directory. Though, he has a number of non-related files I do not have. I only have MRJToolkit.jar.

Or might it be that installation of Java updates overwrites the directory? Checking with my friend for further info.
