Сегодня я получил эту ошибку, когда пытался создать базу данных. Ошибка:

Строки, в которых говорится об ошибке: 

    private String getPrefix(long guildId) {
        try (final PreparedStatement preparedStatement = SQLiteDataSource
// Line 55 Under that text
            .getConnection()
                // language=SQLite
                .prepareStatement("SELECT prefix FROM guild_settings WHERE guild_id = ?")) {

            preparedStatement.setString(1, String.valueOf(guildId));

            try (final ResultSet resultSet = preparedStatement.executeQuery()) {
                if (resultSet.next()) {
                    return resultSet.getString("prefix");
                }
            }

Другой: 

    @Override
    public void onGuildMessageReceived(@Nonnull GuildMessageReceivedEvent event) {
        User user = event.getAuthor();

        if (user.isBot() || event.isWebhookMessage()) {
            return;
        }

        final long guildId = event.getGuild().getIdLong();
// Line 36 Under that text
        String prefix = (String) VeryBadDesign.PREFIXES.computeIfAbsent(guildId, this::getPrefix);
        String raw = event.getMessage().getContentRaw();

        if (raw.equalsIgnoreCase(prefix + "shutdown")
                && user.getId().equals(Config.get("owner_id"))) {
            LOGGER.info("Shutting down");
            event.getJDA().shutdown();
            BotCommons.shutdown(event.getJDA());

            return;
        }

        if (raw.startsWith(prefix)) {
            manager.handle(event, prefix);
        }
    }

И они находятся в моем классе Listener. Я пробовал несколько вещей, но мне это не помогло. Я пытался получить помощь от своего друга, но они тоже не знали решения. Итак, если вы знаете решение, пришлите мне свое предложение. (Я использовал zaxxer и Hikari)
