ユーザーを認証するためのネイティブ呼び出しを行うクラスが 1 つあります。任意の時点で、このクラスの 50 ～ 100 個のオブジェクトがユーザーを認証しようとしている可能性があります。ネイティブ呼び出し関数の実行時間はミリ秒単位ですが、結果が返されると、結果が別のオブジェクトにマップされ、認証が失敗します。

例 -

public class AS400Invoker {
    native String authenticateUser(String message, String channelNo);
    native String changePin(String message, String channelNo);
    private Logger logger = Logger.getLogger(AS400Invoker.class);
    static {
        System.loadLibrary(PropertiesBean.readProperty("libraryname"));
    }
    public String userAuthetication(String ucid, String phoneCode, String pin, String channelNo){
        String toRet = null;
        try {
            logger.info("["+ucid+"] Inside user authentication function");
            logger.info("["+ucid+"] phone code received from IVR: "+phoneCode);
            logger.info("["+ucid+"] channel number received from IVR: "+channelNo);
            UserAuthentication ua = new UserAuthentication();
            String formedMessage = ua.authenticateUser(ucid, phoneCode, pin);
            logger.info("["+ucid+"] user authentication formed message length: "+formedMessage.length());
            logger.info("["+ucid+"] calling native function to authenticate user....");
            if(null != formedMessage)
                toRet = authenticateUser(formedMessage, channelNo);
            logger.info("["+ucid+"] response received from native function: "+toRet);
        }catch(RuntimeException e){
            logger.error("["+ucid+"] Runtime exception occured", e);
        }catch(Exception e){
            logger.error("["+ucid+"] Generic exception occured", e);
        }
        return toRet;
    }
    public String pinChange(String ucid, String phoneCode, String pin, String cif, String channelNo){
        String toRet = null;
        try {
            logger.info("["+ucid+"] Inside pin change function");
            logger.info("["+ucid+"] phone code received from IVR: "+phoneCode);
            logger.info("["+ucid+"] CIF received from IVR: "+cif);
            logger.info("["+ucid+"] channel number received from IVR: "+channelNo);
            PinChange pc = new PinChange();
            String formedMessage = pc.changePin(ucid, phoneCode, pin, cif);
            logger.info("["+ucid+"] pin change formed message length: "+formedMessage.length());
            logger.info("["+ucid+"] calling native function to change the pin....");
            if(null != formedMessage)
                toRet = changePin(formedMessage, channelNo);
            logger.info("["+ucid+"] response received from native function: "+toRet);
        }catch(RuntimeException e){
            logger.error("["+ucid+"] Runtime exception occured", e);
        }catch(Exception e){
            logger.error("["+ucid+"] Generic exception occured", e);
        }
        return toRet;
    }
}

上記のシナリオでは、ネイティブ呼び出しの結果がごちゃごちゃになります。これらの通話で何が問題になっているのか、誰かに光を当てることができますか? 以下は、同じログのスニペットです。以下のスニペットでは、UCID が 00001081951348702252 であるオブジェクトによって要求が発生しますが、応答は別の UCID 00001080011348671171 にマップされ、実際には、応答は 00001081951348702252 UCID に対するものです。
