Problem description:
====================
Method "public abstract javax.smartcardio.CardTerminal.connect(String protocol)" of Sun's implementation of "PC/SC" smartcard reader I/O engine works wrong on Linux. In case when card is absent in card reader this method throws CardException instead of CardNotPresentException, in the same time method "javax.smartcardio.CardTerminal.isCardPresent()" works properly - it returns "false".
This bug is specific for Linux only, it is absent on Windows.

Test system description:
SuSE 10.0 out of box on Intel Pentium IV;
GemPCTwin (serial version) smartcard reader.
PC/SC framework and drivers from GemPlus site (SuSE package):
http://support.gemplus.com/gemdownload/readers/drivers.aspx?prodid=13&osid=11
