I forgot to close some statements...
For information : in the ResultSet documentation it's specified
that invoking the close() method causes all JDBC and database
ressources to be released, in fact one should do before this a call
to myResultSet.getStatement().close(), otherwise nothing is released.

Thank for your remarks which force me to check my code !
