code: public static <T> void closeQuietly(@Nullable final Iterable<T> iterable) {
          if (iterable != null) {
              iterable.forEach(AutoCloseables::closeQuietly);
          }
      }
docs: Checks if any instance within {@code iterable} implements the
  {@code AutoCloseable} interface and calls close if yes. If an
  exception occurs it is logged instead of propagating it.
