> The compareTo method of ExtendedNumericComparator does not compare correctly UNDEFINED and NULL.
> UNDEFINED should always be smaller than anything but it is not always so when compared with NULL.
> compareTo(NULL, UNDEFINED) returns 1, which is correct
> but
> compareTo(UNDEFINED, NULL) returns 1, and it should return -1.
> This could provoke that queries with indexes do not return the right results when these values are involved.
