Не отображаются данные в таблице TableView

При запуске формы никаких ошибок не выводится, но метод getDoctors() в какой-то момент начинает работать с пустотой, и, думаю, поэтому таблица не заполняется, хотя запрос правильный.

FXML:

@FXML
private void initialize () {
    try {
        doct_id.setCellValueFactory(cellData -> cellData.getValue().getDoctId().asObject());
        doc_name.setCellValueFactory(cellData -> cellData.getValue().getDoctName());
        doc_address.setCellValueFactory(cellData -> cellData.getValue().getDoctAddress());
        doc_phone.setCellValueFactory(cellData -> cellData.getValue().getDoctPhone());
        doc_salary.setCellValueFactory(cellData -> cellData.getValue().getDoctSalary().asObject());
        System.out.println("everything is OK there ");
        ObservableList<Doctors> data = DbLogic.getDoctors();
        doct_table.setItems(data);
    } catch (SQLException  | ClassNotFoundException e) {
        Logger.getLogger(Controller.class.getName()).log(Level.SEVERE, null, e);
    }
}

SQL:

public static ObservableList<Doctors> getDoctors() throws SQLException, ClassNotFoundException {
    String sql = "select * from doctors";
    ResultSet rSet = null;
    try {
        rSet = DBUtil.dbExecute(sql);
    } catch (SQLException e) {
        System.out.println("smth went wrong while get records from server "+e);
        e.printStackTrace();
        throw e;
    }
    try {
        ObservableList<Doctors> doclist = FXCollections.observableArrayList();
        while (rSet.next()){
          int id = rSet.getInt("ID");
          String name = rSet.getString("NAME");
            String phone = rSet.getString("PHONE");
            String address = rSet.getString("ADDRESS");
            int salary = rSet.getInt("SALARY");
            System.out.println("id "+id+" "+name+" "+phone+""+salary+"");
            doclist.add(new Doctors(id, name,  phone, address, salary));
        }
        return doclist;
    } catch (SQLException ex){
        System.out.println("smth went wrong while load data from table "+ex);
        ex.printStackTrace();
        throw ex;
    }
}

DBUtil:

public static ResultSet dbExecute (String sqlQuery) throws SQLException, ClassNotFoundException {
    Statement stmt = null;
    ResultSet rs = null;
    try (CachedRowSet crs = RowSetProvider.newFactory().createCachedRowSet()) {
        try {
            dbConnect();
            stmt = connection.createStatement();
            rs = stmt.executeQuery(sqlQuery);
            crs.populate(rs);
        } catch (SQLException e) {
            System.out.println("smth went wrong in dbExecute! " + e);
            throw e;
        } finally {
            if (rs != null) {
                rs.close();
            }
            if (stmt != null) {
                stmt.close();
            }
            dbDisconnect();
        }
        return crs;
    }
}

Doctors:

public class Doctors {
private IntegerProperty idProperty;
