[Oracle] VARCHAR2_SET non riconosciuto nelle nuove versioni JDBC?

[NeoMic]

Ciao a tutti,
in seguito ad aggiornamento software sia di SQLDeveloper(v. 19.2.1.247) che di JDeveloper(v. 12.2.1.4.0) ottengo errore a seguito di una query SQL dove vado ad estrarre un attributo con tipo VARCHAR2_SET(),
l'errore è il seguente:

Creazione descrittore non riuscita: Unable to resolve type "FMSUITE.VARCHAR2_SET"

Stesso errore quando viene eseguita la query tramite il seguente codice su Weblogic:

import javax.naming.InitialContext;
import javax.sql.DataSource;

[...]

public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    response.setContentType(CONTENT_TYPE);
    PrintWriter out = response.getWriter();           
    Connection conn = null;
    PreparedStatement ps = null;
    ResultSet rs = null;
    
    try {
        context = new InitialContext();
        jdbcURL = (DataSource) context.lookup(JNDI);
        conn = jdbcURL.getConnection();
        ps = conn.prepareStatement("select ROLES from UI_MSG_ALERT_ALL", ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
        rs = ps.executeQuery(); // <-- Eccezione
        
        if (rs.next()) {
            Array roles = rs.getArray("ROLES");
            String[] values = (String[])roles.getArray();
            if(values.length == 0) {
                out. append("<b>select ROLES from UI_MSG_ALERT_ALL eseguito con successo!</b>");
            }
        }
    }
    catch (Exception e) {
        e.printStackTrace();
    }
    finally {
        try {               
            rs.close();
            ps.close();               
            conn.close();           
        } catch (SQLException e) {
            out. append("<b>Impossibile chiusura connessione con DB!</b>");
            out. append("<br/><b>" + e.getMessage() + "</b>");
        }           
    }
}

A qualcuno è già capitato questo tipo di errore? Non riesco a trovare una soluzione, la tabella c'era già da prima e con la versione precedente non ottenevo questo errore.

Lo stacktrace:
