FINE: Could not decode 8307 using the built-in EPSG database

authority "European Petroleum Survey Group" found for object of type
"CoordinateReferenceSystem".

The code:
{code}
public CoordinateReferenceSystem createCRS(int srid, Connection cx) throws
SQLException {
// if the official EPSG database has an answer, use that one
CoordinateReferenceSystem crs = super.createCRS(srid, cx);
if(crs != null)
return crs;
// otherwise try to decode the WKT, most of the time it's invalid, but
// for new codes they learned the proper WKT syntax
String sql = "SELECT WKTEXT FROM MDSYS.CS_SRS WHERE SRID = " + srid;
{code}
Is set to check for a null result- but not an exception.
{code}
CoordinateReferenceSystem crs=null;
try {
crs = uper.createCRS(srid, cx);
} catch (org.opengis.referencing.NoSuchAuthorityCodeException notFound ){
// check oracle in the next section
}
...
{code}
