If you build the jar on another computer, does the server run on the computer which it fails?

If you can't do that, does 1.8.6 Vanilla run on that same computer?

Comment by David Lisborg [ 26/May/15 ]

Yes ofcourse, I have a 1.8.1 server running right now. All version after 1.8.3 and forward has given this error.

David, Are you building on a machine that has the requirements? an Error like this usually occurs because the tests run out of resources to complete

Computer powerful enough to run Minecraft
1GB of free disk space.
2GB of memory, at least 1GB free. (Minimum for Minecraft).
Java 7 or Java 8 installed. (Recommended for Minecraft).
Git & Bash installed.

Much appreciated! I dont think this is related to buildtools specifically though. As if I build a spigot on another machine, move it to this machine and start the server I will get the same error when someone connects to the server as it crashes.

I have actually not tested a normal minecraft 1.8.3+ but from what I've read it should cause the same. Seems to be something with Java and how it fetches CPU info from registry. I might be far out of my league, this is just what I've read around the net. All and any help is most welcome. You are doing a really great work!

I can confirm that this is issue is present for a number of users - @GingerGeek does lots of work on BuildTools and I've contacted him to see if he can help at all.
