This seems to be an issue with lwjgl which is fixed since 3.1.5. I locally updated lwjgl in playn to 3.1.6 and the error disappears.

UPDATE just recompiling playn locally also makes the error disappear, so it seems to have nothing to do with lwjgl. But rather with playn being built with java 9 (as far as I can tell from the MANIFEST) and me using java 8 locally.

Just tried the latest release 2.0.4 and could no longer see the problem. 😃

I don’t have JDK 9 installed, but instead created a PR with your suggestion above.

~Also tried using the 2.1-SNAPSHOT but getting the same error.~

Edit: My bad… issue at my end.
