Sun PKCS#11 provider ignores the PIN while loading keystore in Windows JRE

Question

We are using smart card based login in our GUI application. We use active client for Card reader. We are using sun PKCS#11 provider to read certificate from the CARD. In the code we are passing PIN while loading the keystore. It seems the pin is getting ignored and we get active client pin dialog.
PS: In linux JRE the pin passed while loading keystore is working properly.
Below is the code snippet that i used for testing.
public static void  main(String arg[]) throws Exception
       try
         //Create our certificates from our CAC Card
        String configName = "card.config";
         Provider p = new sun.security.pkcs11.SunPKCS11(configName);
         Security.addProvider(p);
         char[] pin = { '1', '2', '3', '4', '5', '6' };
         KeyStore cac = null;
         cac = KeyStore.getInstance("PKCS11");
         cac.load(null, pin);
         showInfoAboutCAC(cac);
      catch(Exception ex)
         ex.printStackTrace();
         System.exit(0);
   public static void showInfoAboutCAC(KeyStore ks) throws KeyStoreException, CertificateException, FileNotFoundException, IOException
      Enumeration<String> aliases = ks.aliases();
       int count = 0;
      while (aliases.hasMoreElements()) 
         String alias = aliases.nextElement();
         X509Certificate[] cchain = (X509Certificate[]) ks.getCertificateChain(alias);
         if (cchain != null){
         System.out.println("Certificate Chain for : " + alias);
         for (int i = 0; i < cchain.length; i ++)
            System.out.println(i + " SubjectDN: " + cchain.getSubjectDN());
System.out.println(i + " IssuerDN: " + cchain[i].getIssuerDN());
content of card.config is
name = myConfig
library = C:\\WINDOWS\\system32\\acpkcs211.dll
Alternative we can see the same behaviour if we run the following command
keytool -keystore NONE -storetype PKCS11 -providerClass sun.security.pkcs11.SunPKCS11 -providerArg "E:\work1\card.config" -list
This command will ask ping in the command line and again active client PIN diaolog will be prompted.
Please let me know if this a bug in Sun PKCS#11 provider in Windows and is there any work around to fix the issue.
Enviornmnet Details::
OS Win XP sp3
Java version "1.6.0_17"
Active client library version :
P11 Library:
Name:  acpkcs211.dll
Version: 4-0-0-12

Answer 1

The program is just to simulate the issue. I understand that user have to pass the pin. In our GUI we have our own dialog to get the pin from user and pass it to the PKCS#11 provider that uses the pin while loading the keystore.
cac.load(null, pin); // the pin passed in load method is not used at all
My problem here is even after the proper pin is supplied by the user the active client PIN dialog is prompted. Whereas in LInux JRE this works fine.
We have a command line application where active client dialog popup is not acceptable. We need to get the PIN from user as command argument and load the keystore.
Please let me know if this clarifies the confusion.
Thanks,
