PG 8.2's JDBC, and Statement.executeUpdate(String, String[]) causing AbstractMethodError - Mailing list pgsql-jdbc

Hello all,

I'm getting a:

AbstractMethodError:
org.postgresql.jdbc2.Jdbc2Statement.executeUpdate(Ljava/lang/String;[Ljava/lang/String;)I

when I call Statement.executeUpdate(String, String[]) on the PG 8.2
distro's JDBC driver (I did not check any other versions).

Is there anything I should check in terms of my settings? I recall
seeing a discussion about prepared stmts being server side now, not in
the driver... and I am using the 'stringtype=unspecified' JDBC URL
parameter; not sure if this could be related.

Thanks in advance,

ken
