Error Invalid number of points in LinearRing (found 3 - must be 0 or >= 4)

Hello,

I use GeoServer with Oracle 10g R2 datastore and i get this error if i want to display a polgon geometry with line graphic representation.

It's not conventional geometry form but others GIS application like Geomedia can display this geometry anomaly.

Here is the instructions to make the contexte of reproducing of the error :

create table geoserver_crash_geometry (id number(10),geometry1 msdsys.sdo_geometry, constraint geoserver_crash_geometry_pk primary key(id));

insert into user_sdo_geom_metadata (table_name, column_name,diminfo, srid )
values('GEOSERVER_CRASH_GEOMETRY','GEOMETRY1',mdsys.sdo_dim_array(mdsys.sdo_dim_element('x',100000,1100000,0.001),mdsys.sdo_dim_element('y',-300000,700000,0.001),mdsys.sdo_dim_element('z',-1000,10000,0.001)),NULL);

commit;
create index geoserver_crash_geometry$idgeo on geoserver_crash_geometry(geometry1) indextype is mdsys.spatial_index;

insert into geoserver_crash_geometry values(1,
MDSYS.SDO_GEOMETRY(3003,null,null,
MDSYS.SDO_ELEM_INFO_ARRAY(1,1003,1),
MDSYS.SDO_ORDINATE_ARRAY(
849566.389999911,108739.620002377,0,
849557.649999911,108752.030002381,0,
849566.389999911,108739.620002377,0
))
);
commit;

Best regards.
