Renew security token on Java after failed try

Question

I have developed code to check if a certain security token is found in the PC prior to a certain operation. The code I am using right now to get the keystore is:

    private KeyStore getKeyStore() {
            try {
                    KeyStore keyStore = KeyStore.getInstance("PKCS11",getProvider()); //$NON-NLS-1$
                    char [] pin = "mypin".toCharArray();
                    keyStore.load(null, pin);

                    return keyStore;
            } catch (Exception e) {
                    e.printStackTrace();
            } 
            return null;
    }

    private Provider getProvider() throws ClassNotFoundException, 
        NoSuchMethodException, SecurityException, InstantiationException,
        IllegalAccessException, IllegalArgumentException, InvocationTargetException {
        Class<?> lclass = ClassLoader.getSystemClassLoader().getParent().loadClass("sun.security.pkcs11.SunPKCS11"); //$NON-NLS-1$
            @SuppressWarnings("rawtypes")
            Constructor constructor = lclass.getConstructor(String.class);
            return (Provider) constructor.newInstance(configName);
    }

If the security token (a USB smartcard) is present the first time the application tries to access the keystore, it runs smoothly without error; but when the smart card is not present the first time the applications tries to get the token, the KeyStore.getInstance raises this exception:

Caused by: java.security.NoSuchAlgorithmException: no such algorithm: PKCS11 for provider       SunPKCS11-eToken

at sun.security.jca.GetInstance.getInstance(Unknown Source)
at java.security.Security.getImpl(Unknown Source)
... 35 more

After this first try, if I plug back the security token, and retry the operation, I get exactly the same error.

Is the SunPKCS11 class caching some data? If so, is there any way to clear this cache?

Thanks for your attention, and please forgive my spelling. English is not my native language.

The stacktrace is not complete. I assume that the most interesting part is hidden in the "... 35 more" part because NoSuchAlgorithmException is used in this context as a Exception wrapper. — Robert, Oct 31 '11 at 12:39
That's the whole stack trace I get. Even though, I was expecting it when the USB is not present. — Josep Rodríguez López, Oct 31 '11 at 12:43
You can print the full stack trace by code: http://stackoverflow.com/questions/1043378/print-full-call-stack-on-printstacktrace/1043461#1043461 — Robert, Oct 31 '11 at 14:24
I have added the stack trace using the "getStackTrace" function from the Exception class. — Josep Rodríguez López, Oct 31 '11 at 15:42
Not relevant to your question, but `Constructor constructor = ...; return (Provider) constructor.newInstance(...)` can be better phrased as `Constructor constructor = ...; return constructor.newInstance(...)`. — Mike Samuel, Oct 31 '11 at 16:06
By the way, I have tested in linux the same code, and it works fine, I guess its a driver issue. — Josep Rodríguez López, Oct 31 '11 at 16:33
