Java Security

This is my code, I in the execution the provider was registered successfully, then I called this method.

{color:#0000ff}System.out.println("Start establish Keystore......");
char [] pin = {'1', '2', '3', '4','5','6','7','8'};

KeyStore smartCardKeyStore = KeyStore.getInstance("PKCS11",pkcs11Provider); *<- It always stucked at here.*{color}*
{color:#0000ff}smartCardKeyStore.load(null, pin);
System.out.println("Type= " + smartCardKeyStore.aliases());
System.out.println("Type= "+smartCardKeyStore.getType());
System.out.println("Provider= "+smartCardKeyStore.getProvider());

Enumeration aliasesEnum = smartCardKeyStore.aliases();
System.out.println("Has more entry= "+aliasesEnum.hasMoreElements());
while (aliasesEnum.hasMoreElements()) {
String alias = (String)aliasesEnum.nextElement();
System.out.println("Alias: " + alias);
X509Certificate cert =
(X509Certificate) smartCardKeyStore.getCertificate(alias);
System.out.println("Certificate: " + cert);
PrivateKey privateKey =
(PrivateKey) smartCardKeyStore.getKey(alias, null);
System.out.println("Private key: " + privateKey);
}

System.out.println("Established Keystore successfully......\n");{color}
after this execute, one exception was throwed....

{color:#ff6600}Start unregister PKCS11......
Unregistered successfully.....
