Hi Mike, thanks for your reply. The version of the pcsclite is the one which is shipped with OSX Lion. pcscd -v reports version 1.4.0. As written in my original post I replaced the stock ccid driver with a pached 1.4.9 version in order to support my Springcard NFC terminal. However, the problem also occurs working only with my Reiner-SCT terminal which does not make use of the ccid driver but has its own driver.
I also took a detailed look into the logs written by the JVM. Below I there is the stack trace showing where the problem occurs. The interesting thing is that even if the stack trace shows problems while listing the attached readers, my program always properly shows the readers prior to terminating due to the seg fault.
