"an arcpolygon geometry has fewer than five coordinates"
*Cause: A geometry, specified as being an arcpolygon, has fewer than five
coordinates in its definition.
*Action: An arcpolygon must consist of at least five coordinates.
An arcpolygon consists of an ordered sequence of arcs,
each of which must be described using three coordinates.
Since arcs are connected the end-point of the first is the
start of the second and does not have to be repeated.
Correct the geometric definition, or set the appropriate
SDO_GTYPE or SDO_ETYPE attribute for this geometry.
