[Geotools-gt2-users] Transformation from EPSG 4326 to 4979

I am using a PostGres/PostGIS 8.3 database with gt-epsg-postgresql 
plugin. The EPSG Geodetic Parameter Dataset has been loaded into 
postgres from EPSG version 7.6.

When I try to transform a geometry from EPSG:4326 (2D CRS) to EPSG:4979 
(3D CRS) I get the following:

Caused by: org.opengis.referencing.operation.OperationNotFoundException: 
No transformation available from system "EllipsoidalCS[Ellipsoidal 2D 
CS. Axes: latitude, longitude. Orientations: north, east. UoM: degree]" 
to "EllipsoidalCS[Ellipsoidal 3D CS. Axes: latitude, longitude, 
ellipsoidal height. Orientations: north, east, up. UoM: degree, degree, 
metre.]".

It seems to me that 2D to 3D transform should be simple (just add a 0 
value for Z axis). Is there a way to do this? If not, shall I file an 
RFE? Thanks for your help.
