C_Login for PKCS11 slot 1 failed. (CKR_USER_ANOTHER_ALREADY_LOGGED_IN)

[EduardoDiNizo]

When I try to perform my tests I get this exception. Does anyone know how to solve this?

------------------ Code -------------------------------------------------------------------------------------
BouncyCastleProvider bcProvider = new BouncyCastleProvider();
Security.addProvider(bcProvider);
Connection connection = null;
try {
connection = new Connection();
} catch (IOException e) {
e.printStackTrace();
}
KeyStore ks = KeyStore.getInstance("PKCS11", "OpenSC-PKCS11");
PKCS11LoadStoreParameter params = new PKCS11LoadStoreParameter(); params.setSOProtectionPIN("0000".toCharArray());
params.setProtectionPIN("0000".toCharArray());

    PKCS11SessionStore sessionStore = new PKCS11SessionStore();
    sessionStore.open(connection.getProvider(),params);
    System.out.println(sessionStore.getSession().isUserLoggedIn());

    ks.load(params);

CKR_USER_ANOTHER_ALREADY_LOGGED_IN: This value can only be returned by C_Login. It indicates that the specified user cannot be logged into the session, because another user is already logged into the session. For example, if an application has an open SO session, and it attempts to log the normal user into it, it will receive this error code.
