Polar Stereographic Issue with EPSG 32661/32761

Hi everyone,

I got a projection issue with GS (1.7 + 2.0) for Polar Stereographic
projections EPSG:32661 (WGS 84 / UPS North) and EPSG:32761 (WGS 84 /
UPS South). It seems that the axis are swapped in the EPSG DB v6.12.0.

Here is the definition used by Geoserver/Geotools:

PROJCS["WGS 84 / UPS North",
  GEOGCS["WGS 84",
    DATUM["World Geodetic System 1984",
      SPHEROID["WGS 84", 6378137.0, 298.257223563, AUTHORITY["EPSG","7030"]],
      AUTHORITY["EPSG","6326"]],
    PRIMEM["Greenwich", 0.0, AUTHORITY["EPSG","8901"]],
    UNIT["degree", 0.017453292519943295],
    AXIS["Geodetic longitude", EAST],
    AXIS["Geodetic latitude", NORTH],
    AUTHORITY["EPSG","4326"]],
  PROJECTION["Polar Stereographic (variant A)", AUTHORITY["EPSG","9810"]],
  PARAMETER["central_meridian", 0.0],
  PARAMETER["latitude_of_origin", 90.0],
  PARAMETER["scale_factor", 0.994],
  PARAMETER["false_easting", 2000000.0],
  PARAMETER["false_northing", 2000000.0],
  UNIT["m", 1.0],
  AXIS["Northing", "South along 180 deg"],
  AXIS["Easting", "South along 90 deg East"],
  AUTHORITY["EPSG","32661"]]


Here is the definition from spatialreference.org:

PROJCS["WGS 84 / UPS North",
    GEOGCS["WGS 84",
        DATUM["WGS_1984",
            SPHEROID["WGS 84",6378137,298.257223563,
                AUTHORITY["EPSG","7030"]],
            AUTHORITY["EPSG","6326"]],
        PRIMEM["Greenwich",0,
            AUTHORITY["EPSG","8901"]],
        UNIT["degree",0.01745329251994328,
            AUTHORITY["EPSG","9122"]],
        AUTHORITY["EPSG","4326"]],
    UNIT["metre",1,
        AUTHORITY["EPSG","9001"]],
    PROJECTION["Polar_Stereographic"],
    PARAMETER["latitude_of_origin",90],
    PARAMETER["central_meridian",0],
    PARAMETER["scale_factor",0.994],
    PARAMETER["false_easting",2000000],
    PARAMETER["false_northing",2000000],
    AUTHORITY["EPSG","32661"],
    AXIS["Easting",UNKNOWN],
    AXIS["Northing",UNKNOWN]]

As a result different datasets are rendered wrong: Instead of sitting
in the southeastern part (as in e.g.
http://nsidc.org/data/atlas/epsg_32661.html), Geoserver renders Europe
in the NW.

Can someone confirm that this is a EPSG DB problem and explain how to
fix it the easiest way?

Thanks,
Torsten
