One thought:

What about returning Statement.SUCCESS_NO_INFO as it says in
http://docs.oracle.com/javase/6/docs/api/java/sql/BatchUpdateException.html#getUpdateCounts%28%29
and
http://docs.oracle.com/javase/6/docs/api/java/sql/Statement.html#executeBatch%28%29

?

It seems better to report no number at all rather than a number
(INT_MAX) that is known to be wrong.
