Hi!
I encountered really strange behaviour from the geotools 2-2 library when using
an UTM (transform zone 31 north). With assertions enabled, transforming a WGS84
geographical coordinate where the longitude is 0 throws the following exception:
java.lang.AssertionError: The transform result may be 0.095 meters away from
the expected position. Are you sure that the input coordinates are inside this
map projection area of validity? The point is located 3°00.0'W away from the
central meridian and 63°00.0'N away from the latitude of origin.

org.geotools.referencing.operation.projection.MapProjection.transform(MapProjection.java:643)
at
org.geotools.referencing.operation.projection.MapProjection.transform(MapProjection.java:678)
The above exception was generated using the coordinate 63.0N 0.0E and the
transform:
PARAM_MT["Transverse_Mercator",
PARAMETER["semi_major", 6378137.0],
PARAMETER["semi_minor", 6356752.314245179],
PARAMETER["central_meridian", 3.0],
PARAMETER["latitude_of_origin", 0.0],
PARAMETER["scale_factor", 0.9996],
PARAMETER["false_easting", 500000.0],
PARAMETER["false_northing", 0.0]]
The really strange thing is that changing the longitude to 0.01 or -0.01 will
not generate any assertions. Is my thinking totally stupid here or has anyone
else encountered something similar.
Best regards,
