Problem description:
====================
Sun's implementation of "PC/SC" smartcard reader I/O engine works wrong.
RI implementation of "public TerminalFactory CardTerminal.getTerminalFactory()" returns null instead reference on factory used for CardTerminal creation.

Please run the minimized test to reproduce failure.
Issue appears on Windows XP with Gemplus "GemPCTwin" smart card reader for serial port.

Minimized test:
===============

--- test.java ---
import javax.smartcardio.*;
import java.security.*;
import java.util.*;

public class test {

    public static void main(String[] args) throws CardException,
        NoSuchAlgorithmException {
        
        TerminalFactory factory = TerminalFactory.getInstance("PC/SC", null);

        List<CardTerminal> cardTermList = factory.terminals();
    
        if( cardTermList.size() != 0) {
    
            CardTerminal cardTerm = cardTermList.get(0);
    
            TerminalFactory returned = cardTerm.getTerminalFactory();
    
            if (returned == null) {
                System.out.println("Failed. CardTerminal.getTerminalFactory() returns null.");
                System.out.println("TerminalFactory object toString:" + factory.toString());
                System.out.println("CardTerminal object toString:" + cardTerm.toString());
            } else {
                System.out.println("Passed.");
            }
    
        } else {
            System.out.println("Cannot be reproduced - card terminal (reader) absent.");
        }
    }
