Dyre Tjeldvoll commented on DERBY-3203:
---------------------------------------
I think I have resolved the apparent mystery here. 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)?
