Ubuntu 18.04. I shall look for a ppa with newer tomcat.
It's a VM, I could go to Core 20.

I could go to 8G for the VM if you think that's relevant.
My reading is that I'm not even using 1G of ram at this point.
No, it's not in Amazon. It's a Dell Xeon workstation in the basement of my
wife's clinic. Patient record confidentiality would probably contraindicate
EC2 :-)

I installed it there to grep/read them, then decided that I'd install that on
my desktop.

Yes, exactly.

No, I'm not building myself.
There is an oscar.deb, which btw, results in the same 100%.
It also does other stuff like configure mariadb locally (which I don't want).
But, I've used the oscar.war from that deb, and also the oscar.war which
is on the bare-metal version that is running.

No, it's in error.

I think that the cp of the 220M oscar.war hasn't completed when it starts
that first deploy. That's why the ZIP error.

This is the only time I've seen this error, I've also used the manager web
application before.

I have an ssh -L 8080:192.168.2.9:8080 tunnel from my desktop.
There is nothing else in between.

I tried that. It says something about there being no socket open.
My impression is that "jstack" was an Oracle Java only tool.
