A CRS lookup with SRID of 4326 returns lat/long. When serializing a FeatureDataAdapter or a FeatureWritable, the Axis orientation is not preserved. IN some cases, when deserialized, lat/long is assummed. This the Axis orientation must be preserved. This also respects that input data may in fact be lat/long.

If the input data is long/lat and is serialized into an intermediate file (sequence file, for example) and then read back, the FeatureWritable assumes lat/long.
