ResultSet not closed on new execution of Statement

I noticed with Hibernate I sometimes get java.sql.SQLException: There is an open result set on the current connection, which must be closed prior to executing a query when retrieving a result, depending on the complexity of the entity I am loading. Apparently Hibernate is relying on the specified behavior of the Statement to implicitly close any open ResultSet when performing a new execution.

I worked around this in a local branch with the following code:

protected boolean execute(Query query) throws SQLException {

    synchronized (protocol) {

        if (protocol.activeResult != null) {

            protocol.activeResult.close();

        }

        // snip

    }

}
