ScrollableCursor from EclipseLink throws SQLException: The result set is closed. on remote env

问题

I have problem with ScrollableCursor. On my local environment it works well but on remote env I got exception:

Internal Exception: java.sql.SQLException: The result set is closed. Error Code: 0 at org.eclipse.persistence.exceptions.DatabaseException.sqlException(DatabaseException.java:340) at org.eclipse.persistence.internal.databaseaccess.DatabaseAccessor.processExceptionForCommError(DatabaseAccessor.java:1620) at org.eclipse.persistence.queries.ScrollableCursor.getPosition(ScrollableCursor.java:251) at org.eclipse.persistence.queries.ScrollableCursor.retrieveNextObject(ScrollableCursor.java:551) at org.eclipse.persistence.queries.ScrollableCursor.loadNext(ScrollableCursor.java:411) at org.eclipse.persistence.queries.ScrollableCursor.hasNext(ScrollableCursor.java:277)

My query:

private static final String SELECT_QUERY = "SELECT"
        + " new MyObjectDto(object.id, object.time)"
        + " FROM ObjectEntity object"
        + " WHERE object.msgDateTime < :startDateTime ";


@Override
    public ScrollableCursor getScrollableCursor(LocalDateTime startDateTime) {
        TypedQuery<ScrollableCursor> query = createQuery(SELECT_QUERY, ScrollableCursor.class)
                .setParameter("startDateTime", startDateTime)
                .setHint(QueryHints.SCROLLABLE_CURSOR, HintValues.TRUE);

        return  query.getSingleResult();
    }

Could you please give me some ideas what can be wrong?
