Problems with spatial data

[roger]

Run the following script to create and populate a table in either 4.1.11 or 5.0.4 beta:

use test;
create table if not exists test_spatial (id int not null auto_increment primary key, geom Point null);
insert into test_spatial (geom) values (PointFromText('Point (1.0 1.0)'));

Using Connector/J 3.1.7 or 3.1.8 the following message is displayed when we do the following:

PreparedStatement ps = connection.prepareStatement("select * from test_spatial");
ps.execute();

"Unknown type '255 in column 1 of 2 in binary-encoded result set."

Connector/J 3.0.16 works fine, but it does not support the new DBMS features of 4.1 and 5.0

What may be wrong?
