Javac for Building the PrismLauncher on Ubuntu

I peridocially fall of the wagon and get drawn back into playing Minecraft. I’ve decided that, in order to make this time not wasted, I need to do something constructive with this urge.

And, since often this is deployed in data centers where non-standard ports are blocked, it means that the HTTPS really needs to be supported on the proper port, which is 443. Here are the range of options.
