I thought that maybe can be a Java problem, do you know some software to do 
this kind of test (parallelism) ? I'll check if pcsc-tools can do that...
I guess it is a javax.smartcardio "limitation".

You need to create one context per reader using SCardEstablishContext.
I bet the Java wrapper creates only one context for all the readers.
In pcsc-lite the context is associated to a mutex. So all your
commands will block on the same mutex even if they use different
readers.
I don't know if is it easy or even possible to avoid this Java wrapper
"feature".
Hello

One possible method would be to use JNA to talk directly to libpcsclite.so (or winscard.dll on windows)
This would allow you to use the pcsclite C API from java.

Best regards
