	at com.mysql.jdbc.ResultSet.absolute(ResultSet.java:2137)

This error doesn't occurs when using Statement. It only occurs when using PreparedStatement.

- MySQL server 4.1.1-alpha on Linux. (Mandrake 8.1)
- mysql-connector-java-3.1-nightly-20040203-bin.jar (on Win98) 
- JSDK 1.4.2 b-28 (on Win98)
- Apache Tomcat 4.1.29 (on Win98)

As far as I remember, it worked with MySQL-4.1.0 and mysql-connector-java-3.1.0-alpha-bin.jar.
I tried to downgrade to mcj3.1.0.alpha, but it seems to be incompatible with MySQL 4.1.1, so I can't test.

How to repeat:
PreparedStatement pstmt=conn.prepareStatement("select * from test");
ResultSet rs=pstmt.executeQuery();
rs.absolute(11); //the error occurs here (the test table has about 30 rows)
while (rs.next())
  int val= rs.getInt(1);
