I'm guessing its a problem with apache commons not being java 9, rather
than OC.

Ironically, the Java version checker OC is trying to call isn't there
anymore. I'm not sure what checker other mods use, but OC was the only mod
out of my ~200 other jarmods that wouldn't start with Java 9.

With Java 9 being experimental and all, this is obviously a low priority
issue. But fixing it now would help us find more Java 9 bugs in the future

I think you're right.

https://issues.apache.org/jira/browse/LANG-1027

Looks like an old issue though.

Anything I could do on my end to work around the issue? Or would we have to add a workaround here:
https://github.com/MightyPirates/OpenComputers/blob/master-MC1.7.10/src/main/scala/li/cil/oc/common/SaveHandler.scala#L201

EDIT: facepalm I'll try updating the libs, 1 sec.

EDIT2: Lang 3.4 isn't out yet, I'll have to try building it myself. :(

Yup, confirmed the issue isn't with OpenComputers. I built Apache Lang 3.4 myself, and Java 9/OC works fine.

I blame Cirno.
