How did you compile the mod?

It may not be the source of your problem, but build 1708 is neither recommended nor most recent. To get the best help with 1.8.9, you should probably update to the most recent build. If you look at all the bug fixes in the changelog, you'd understand why those in-the-know wouldn't want to sort errors in an old build.
