Cause is a direct call to Libraries.bind, without and accompanying Libraries.loadLibrary

Fix is simple:

- private static final OutOfBounds lib = Libraries.bind(MethodHandles.lookup(), OutOfBounds.class);
+ private static final OutOfBounds lib = Libraries.bind(OutOfBounds.class, Libraries.loadLibrary(MethodHandles.lookup(), "OutOfBounds"));
