Choosing a Java Version on Ubuntu
Apologies but I had to write this down where I am likely to find it in the future.
I run a fair number of Java based apps that are, shall we say, sensitive as to the edition/version of Java that is being invoked.
Some updates take it upon themselves to “correct” my settings.
I happened upon this and it reminded me of that issue.
Thought you might find it helpful at some point.
