I have already tried the Java 7 workaround, which isn't working. Help?

Did you "Open with Java Web Start Launcher" ?

If not try - if it still doesn't work give info
OS? Bit? Java Path?
Any Firewall besides Windows FW running?
What AV?
How do you connect to Internet? What Routermodel? Connection from your PC to Router by Lan or WLan (WiFi)?

As for me, it is the same problem.
Win 7 64 bit, installed latest JRE 2 days ago, Java 8.25, all 64 bit.
Bitdefender free antivirus (tried to turn it off, doesn't help).

The worst thing is that I am trying to connect from my job (yeah, instead of working on it), and we've got a proxy, so I tunnel stuff through Proxifier. In 99% cases it helps, but not here, I even don't receive connection attempt from JRE in Proxifier. Same with Wurm, they use JRE too.
What ports should be open, aslso do you use TCP or UDP? In case you use UDP, can I translate them into TCP and backwards?

And most of all. Why on Earth do people make games in java?) Just curious, as spent like 3 years battling with java environments in games, showing difficult multithreading experience, low performance etc etc.

That is not the error at all, so it's not enough to say that it's the same problem. The actual error is under the "Exception" tab.

See here for some rationale on language choice. TL;DR: your examples of problems are simply not true.
