We don't officially support Java 10, but that's probably not the issue here.

Was there a stack trace?

[Haringat]

I didn't see one. However, I hadn't started opsu via console and since it crashed right after showing the error dialog I can't be sure.
When I come home I will check if there is a stacktrace as well as whether or not this occurs in Java 8 and 9.

If there was an error, it should be logged to .opsu.log file in your config directory, which is wherever the JAR file is if you got it from the GitHub releases, or ~/.config/opsu/ if you built with -DXDG=true (which is the case if you got it from the AUR).

Note that we also don't officially support Java 9, though it'll probably also still work.

Due to #421 I can't test it with jdk8.
However, I tested it with jdk 9 and 10 with the same result. Here is the log:

Looks like Osu! used an unsigned byte for that value while Opsu! uses Java's byte (which is signed). Thus values >= 128 cause an error. I fixed it and will submit a PR.
