Description

We are unable to create a CoordinateOperation from the WKT that comes from an existing CoordinateOperation object. 
The code below can be used to test this:
 
        CoordinateOperationAuthorityFactory opFactory = (CoordinateOperationAuthorityFactory) CRS.getAuthorityFactory("EPSG");
        CoordinateOperation opFromCode = opFactory.createCoordinateOperation("5630");
        _String operationWKT = opFromCode.toWKT();
        WKTFormat wf = new WKTFormat(null, null);
        CoordinateOperation opFromWKT = (CoordinateOperation) wf.parseObject(operationWKT);_
 
When trying to execute this code the following error is returned:
 

org.apache.sis.io.wkt.UnparsableObjectException: Error in “COORDINATEOPERATION”: Missing value for “tgt_semi_major” parameter.
