Invalid column display size. Cannot be less than zero

Hi all!

I'm using postgresql-8.1-407.jdbc3.jar.

The following code:
CachedRowSet cachedRowSet = new CachedRowSetImpl();
cachedRowSet.populate(resultSet);

raise the following exception:
java.sql.SQLException: Invalid column display size. Cannot be less than
zero
