wrong escaping when having curly bracket in table/field name

try (Connection conn = DriverManager.getConnection("jdbc:mariadb://localhost/testj?user=root&log=true")) {

    Statement stmt = conn.createStatement();

    //will throw java.sql.SQLException: unknown escape sequence {tt1}

    stmt.execute("CREATE TEMPORARY TABLE `{tt1}`(`{Document id}` int, tt text)");

}
