user lacks privilege or object not found: PRODUTO

Estou com o mesma mensagem de erro em minha aplicação. Entro em minha pasta do projeto via terminal cd Downloads/loja-virtual E lá dentro digito para subir o banco

java -cp hsqldb.jar org.hsqldb.server.Server --database.0 file:loja-virtual --dbname.0 loja-virtual

depois com o CTRL + SHIFT +T abro uma nova aba no terminal ainda dentro da minha pasta do projeto e digito o seguinte comando:

java -cp hsqldb.jar  org.hsqldb.util.DatabaseManager

E escolho a seguinte opção: Type: HSQL Database Engine Server com a seguinte url: jdbc:hsqldb:hsql://localhost/loja-virtual

e ao tentar inserir via java na classe de teste de inserção tomo a mensagem de erro informada na stack abaixo.

E a minha stacktrace.

Segue minha classe de conexão.

public class ConnectionPool {
    private DataSource dataSource;

    public ConnectionPool() {
        JDBCPool pool = new JDBCPool();
        pool.setUrl("jdbc:hsqldb:hsql//localhost/loja-virtual");
        pool.setUser("SA");
        pool.setPassword("");
        this.dataSource = pool;
    }

     Connection getConnection() throws SQLException {
        System.out.print("adquirindo conexão...");
        Connection connection = dataSource.getConnection();
        return connection;
    }

Classe de Teste de Inserção

public class TestaInsercao {

    public static void main(String[] args) throws Exception {
        try (Connection connection = new ConnectionPool().getConnection()) {
            connection.setAutoCommit(false);
            String sql = "insert into Produto (nome, descricao) values (?, ?)";
            try (PreparedStatement statement = connection.prepareStatement(sql,

                adiciona("TV LCD", "32 polegadas", statement);
                adiciona("Blueray", "Full HDMI", statement);

                connection.commit();
                statement.close();
            } catch (Exception e) {
                connection.rollback();
                System.out.println("Rollback efetuado");
                e.printStackTrace();
            }
        }
    }

    private static void adiciona(String nome, String descricao,
            PreparedStatement statement) throws SQLException {
//        if (nome.equals("Blueray")) {
//            throw new IllegalArgumentException("Problema ocorrido");
//        }
        statement.setString(1, nome);
        statement.setString(2, descricao);
        boolean resultado = statement.execute();
        System.out.println(resultado);
        try (ResultSet generatedKeys = statement.getGeneratedKeys()) {
            while (generatedKeys.next()) {
                long id = generatedKeys.getLong("id");
                System.out.println("id gerado: " + id);
            }
        }
    }
}

Como corrijo isso?
