javax.smartcardio does not detect cards on Mac OS X

    Details

      Backports

        Description

        FULL PRODUCT VERSION :
        java version "1.7.0_07"
        Java(TM) SE Runtime Environment (build 1.7.0_07-b10)
        Java HotSpot(TM) 64-Bit Server VM (build 23.3-b01, mixed mode)

        ADDITIONAL OS VERSION INFORMATION :
        Mac OS X 10.8.1
        Darwin lambda.local 12.1.0 Darwin Kernel Version 12.1.0: Tue Aug 14 13:29:55 PDT 2012; root:xnu-2050.9.2~1/RELEASE_X86_64 x86_64

        EXTRA RELEVANT SYSTEM CONFIGURATION :
        Connected a ACR38U smartcardreader (CCID)
        Inserted a Belgian eID card in the reader.

        A DESCRIPTION OF THE PROBLEM :
        Smartcards inserted in a smartcardreader are not detected by Oracle's Java 7 for Mac. It detects the reader, but not the card.

        REGRESSION. Last worked in version 6u31

        STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
        connect a reader and insert a smartcard. Then basically do this in Java:

        TerminalFactory factory = TerminalFactory.getDefault();
        CardTerminals cardTerminals = factory.terminals();
        List<CardTerminal> cardTerminalList;
        cardTerminalList = cardTerminals.list();
        for (CardTerminal cardTerminal : cardTerminalList){
            System.out.println(cardTerminal.getName());
            if (cardTerminal.isCardPresent()) {
            // not getting here
           }
        }


        EXPECTED VERSUS ACTUAL BEHAVIOR :
        EXPECTED -
        Expected to detect the card. This works in Mac OS X's own Java 6 VM.
        ACTUAL -
        The card is not detected. The VM acts as if the reader is empty.

        REPRODUCIBILITY :
        This bug can be reproduced always.

        CUSTOMER SUBMITTED WORKAROUND :
        We currently recommend our customers to deinstall Oracle's Java version and to stick with Apple's Java version.
