This is printed in the traceback when trying to generate the voxel mesh in some projects. This error seems seems to only occur in Java 1.8, which according to your build.gradle, you support. I'd be happy to provide more information to help you fix this.

Are you building the sources yourself? This happens when you build the sources with JDK9+ and run it with JDK9<. Some new overriden methods are introduced in the ByteBuffer class in JDK9.

Fix available in release v1.5.1

I'm not building this my self. I'm using your Maven repo, and to my knowledge, JDK 8.
