> Due to JEP416, we are no longer able to set the LocationsOrderInterceptor on
> JDK18+.
> While the code is supposed to catch these instances and still work (just not
> optimally), it does not catch InaccessibleObjectException.
> Catching InaccessibleObjectException is not real fix, but it allows for
> running with JDK18+.
> The real fix would either be avoiding reflection for this (which probably
> requires Hadoop support), or using the sanity-draining workaround for JEP416
> which floats around on stackoverflow.
