Hi ,
I am trying to run java with JNI interface over a shared library that uses
pcsc-lite 1.1.1 library.
a similar C code runs fine with the same pcsc library however running it via
JNI results the following JAVA debug message:
---------JAVA start main
before loading ar_jpk11
after loading ar_jpk11
An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : 11 occurred at PC=0x40018f4c
Function name=pthread_cond_destroy
Library=/lib/libpthread.so.0

It seems the pcsc-lite is not thread safe !!!
Did any one encounter such a problem with running JNI code with muscle?
Was he able to resolve it somehow ?
Thanks.
