Could you try to put in the classpath only one of those? Try:
gt2-epsg-hsql-2.2-RC3.jar
and try again in an other test:
gt2-epsg-wkt-2.2-RC3.jar
and tell me if one is better than the other.
What I'm suspecting: I noticed that the first CRS uses:
DATUM["European Datum 1950(1977)", ...
TOWGS84[-123.02, -158.95, -168.47, 0.0, 0.0, 0.0, 0.0]
while the second CRS uses:
DATUM["European Datum 1950", ..
TOWGS84[-157.89, -17.16, -78.41, 2.118, 2.697, -1.434,
-1.1097046576093785]
Both datum are considered differents, because the names are not exactly the
same. They also have
different TOWGS84 parameters. However I wonder if they were not supposed to be
considered the same.
Because gt2-epsg-wkt do not supports datum shift through Bursa-Wolf parameters,
if gt2-epsg-wkt
gives closer results, then this means that the above-cited datum should be
considered as the same one.
