Public bug reported: The current versions of OpenJDK do not correctly find the libpcsc native C library, causing them to remove PC/SC support silently. This breaks smartcard applications, as javax.smartcardio uses libpcsc to interface with smartcard terminals.
Please see the attached Example.java. It loads the default smartcardio terminal factory, and shows the type. Currently, Java JDK supports two terminal types[0]: "None" (a dummy type which always says there are no terminals) and "PC/SC" (interfaces with PC/SC terminals). The PC/SC terminal factory is the default, but if it cannot be loaded, the Java library silently falls back to "None". Now, on Ubuntu, the library searches for the PC/SC library in /usr/lib and /usr/local/lib, but libpcsclite1 installs its library file in /lib/libpcsclite.so.1.0.0. Therefore, the JDK library fails to find the file, and silently disables smartcard terminal support. To see this, compile the attached Example.java normally and run it: $ javac Example.java $ java Example Terminal factory type: None A workaround[0] is to set the Java system property sun.security.smartcardio.library to the correct location: $ javac Example.java $ java -Dsun.security.smartcardio.library=/lib/libpcsclite.so.1 Example Terminal factory type: PC/SC Note: you don't need to have any terminals attached to see this result. I would like to request the JDK be patched to search for the PCSC library in the correct location, namely /lib, so PC/SC applications can work out-of-the-box without having to supply system properties every time Java is started.
