> The requirement that the argument to ResultSet.setFetchSize(int) be less than 
> Statement.getMaxRows() was dropped in Java 6/JDBC 4, (it is not present in 
> the Java 6 javadoc, but can still be seen in the Java 5 javadoc).
> The reason why the client driver doesn't throw an exception in this case is 
> because am.ResultSet incorrectly checks against ResultSet.maxRows_ and NOT 
> am.Statement.getMaxRows(). So when am.Statement.setMaxRows(int) is called 
> after a result set has already been created, am.ResultSet.setFechSize(int) 
> will check against a stale value.
> The question is what to do about this. The client driver clearly has a bug, 
> but should we fix it by duplicating the old behavior found in the embedded 
> driver, or change both drivers to comply with latest spec which allows any 
> non-negative value as argument to ResultSet.setFetchSize(int)?
