There would at least have to be Arrays.EMPTY_OBJECT_ARRAY *and* private
synthetic constants since the spec. requires that this code works:
public static <T> T[] array(T ... elements) { return elements; }
...
String[] strings = array();
Integer[] integers = array();
...
...
It would be nice to have a method like above in j.u.Arrays then.
