9.1 JDBC 4 driver

Hi,

We have been using 8.4 jdbc3 driver. Recently we have upgraded it to 9.1-901 JDBC 4 jar.  I am getting an error message
(org.postgresql.util.PSQLException:Bad value for type int : 2618079772) while 
updating some columns. The column I am updating is a date column and I am using updateDate function of the rowset. Did
somegoogle search and found a really old post 
(http://archives.postgresql.org/pgsql-jdbc/2007-03/msg00029.php) that talked about oid being returned as Integer and
causingthis problem when the oid is too big. Below I am including the stack trace. 

I have reverted to 8.4 jdbc3 driver and the same code works fine.  So is this a bug in jdbc4?

Thanks,
Prasanth
