javax.smartcardio package not working in Java 7 on OS X ML

Hi,

I have applet that uses javax.smartcardio package to comunicate with smart card! It works on all Windows, Linux and versions before Mac OS X Lion!

But in OS X ML the applet crashes. There is no 32 bit Java 7 to test with it. I don't know if the problem is PCSC library or this reported bug.

Since Java 7 is embeded in browser plugin if I remove it, my applets are not started at all, and I can not use Java 6.

What should I do?

At Thread 45 I see "libj2pcsc.dylib". Is this the pcsc library used by Java to connect to Smard Card readers?

The error mesage starts with :

Hi. Yes, it is the same as the bug you linked.

Solution: replace libj2pcsc.dylib[1] with a fixed library. You can download the one I made here[3], if you trust some random person on the Internet.

Details: I filed a more descriptive bug two months ago but Oracle never acknowledged it. The bug is that Oracle's 64-bit PCSC native library[1] is broken. They included a header file that typedef's DWORD to a 64-bit value, when the PCSC OS X library actually gives you a 32-bit value. The fix is to replace winscard.h[2] with a header that simply #include <PCSC/wincard.h>, #include <PCSC/wintypes.h> and then run the openjdkathome compile. Then replace your JDK7 copy of the library with the fixed one.

Hi Yonathan Randolph,

I have tried your fixed library but nothing happens at all. The problem still remains.

By the way in Mac OS X ML we have no path as /Library/Java/JavaVirtualMachines/jdk1.7.0_17.jdk/Contents/Home/jre/lib/libj2pc sc.dylib. We have libj2pcsc.dylib in /Library/Internet Plug-Ins/JavaAppletPlugin.plugin 1/Contents/Home/lib, since Java 7 is embeded in browser plugin for OS X ML. We have no installed jDK at all. This is client pc.

I would like to ask you for link to the bug you have posted to Oracle.

Thank you

Best Regards, Valentin Ivanov

I cannot address your question, but you should be aware that using Java in the browser is extremely dangerous at this time, and shows no signs of ever becoming safe. See:

Java is vulnerable… Again?!

and:

http://java-0day.com

You should really start finding ways to replace Java in your web browser with other things.

Valentin Ivanov, I’m sorry, but I can’t link to the bug I filed because they never approved it (there’s some kind of moderation before giving bugs a bug id). I can only tell you that it was internal review ID 2396490.

But after successfully compiling OpenJDK with the fix, I sent a message to security-dev@openjdk.java.net.

Any news?

I wrote an Applet that uses javax.smartcardio on Windows and all worked OK. On the Mac -- No dice.

I'm not sure I'm having the same problem -- but it does seem like it to me. Kind of frustrating that it works in Windows land -- but not on the Mac.

Oct 10, 2013 7:33 AM in response to V@lentino

I can confirm the issue here (Mountain Lion, 10.8.5). A very simple program (attached below) that just enumerates terminals and checks if a card is present will crash:

If Apple JDK6 is used in 64-bit mode (without supplying the -d32 argument)
If Oracle JDK7 is used (can not switch to 64-bit, uses)

It will work if:

If Apple JDK6 is forced into 32-bit mode using -d32
If Oracle JDK7 version of libj2pcsc.dylib is replaced with a patched version

javax.smartcardio on Mac OS X is in a truly sad state. :-(

Can anyone suggest alternatives for Smartcard communication on Mac OS X fat clients?

package com.example.smartcardio;

import javax.smartcardio.CardTerminal;

import javax.smartcardio.CardTerminals;

import javax.smartcardio.TerminalFactory;

public class TestWaitForChanges {

public static void main(String[] args) throws Exception {

CardTerminals terminals = TerminalFactory.getDefault().terminals();

while (true) {

for (CardTerminal terminal : terminals.list()) {

System.out.println("Checking terminal: " + terminal.getName());

System.out.println("Card present: " + (terminal.isCardPresent() ? "YES" : "NO"));

}

System.out.println("Waiting for changes...");

terminals.waitForChange();

}

alex.suzuki, are you able to use JNI or JNA? If so, you can talk to the smartcard native library directly. I posted a proof-of-concept smartcardio library callled jna2pcsc, although it is neither finished, nor well-tested as it was not needed at my company.

Yonathan, yes, I should be able to use JNI and JNA (latter is preferred as we wouldn't have to extend our build system to deal with platform-specific native code). Your library looks very interesting. I'll try if it works for my usecase, and get back to you. Thanks a lot!

In May 2014, Oracles’s Ivan Gerasimov fixed waitForChange and supposedly fixed list and isCardPresent as of JRE 7u80, 8u20, and 9. The latter commit is pretty suspicious, so I advise you to test it extensively before declaring the issue fixed. If anyone wants to recompile OpenJDK you can test out the changes yourself.
