aka 7200271 : javax.smartcardio.CardTerminal.isCardPresent always returns false
Dear security, The underlying cause of this issue is silly. The signature of SCardGetStatusChange is wrong on OS X; the JRE code expects DWORD to be uint64_t, but in the OS X system library it’s actually uint32_t. Note that the code is only wrong in OS X; on Linux the PCSC library uses 64-bit longs. The simplest solution is to just not use your own winscard.h, since it’s included with OS X. Alternatively, you could check in a header that declares different types for Linux and OS X[1]. This meant that the following functions returned incorrect values or crashed if you called them too often: TerminalImpl.isCardPresent() TerminalImpl.waitForCard(boolean, long) PCSCTerminals.list() PCSCTerminals.waitForChange(long) I previously submitted a bug report on 2012-12-03 (internal review ID of 2396490) but haven’t heard back so perhaps this is a better forum. Example segfault when you run the attached program: # SIGSEGV (0xb) at pc=0x000000015deb166e # # JRE version: 7.0_17-b02 # Java VM: Java HotSpot(TM) 64-Bit Server VM (23.7-b01 mixed mode bsd-amd64 compressed oops) # Problematic frame: # C [libj2pcsc.dylib+0x166e] pcsc_multi2jstring+0x11 [1]: http://anonscm.debian.org/viewvc/pcsclite/trunk/PCSC/src/PCSC/wintypes.h?revision=5869&view=markup I hope this can be fixed soon as it makes using smartcard very delicate.
