Minimwatch 2, Java and Gnome TopiconsPlus

[nickc]

Reflecting further, and re-reading Simon's instructions for installing Java, I'm wondering if the terminal result I posted refers to the Java in use with a Virtual Machine I have installed. But it doesn't seem to be version 10, which is definitely installed somewhere. Where can I find it? There isn't a Java folder in /usr/local/ and I'm loath to download another copy of Java and unpack to /usr/local/ in case I further muddy already troubled waters. I need a bit better grasp of what I'm trying to do.
