That's exactly what I want. I have one Java application (equals one
TSP) running on one JVM and there I want to instantiate several TCS,
each with one TDDL connection to one TPM.
The problem is: How can I pass different configuration options to each
TCS? I can create multiple contexts (connection between TSP and TCS)
with
TcIContext context0 = new TcTssContextFactory().newContextObject();
but when they accessing TcTcsProperties from inside (i.e. inside TDDL)
they all will get the same property values because it is singleton.

To summarize: I need a possibility to pass different values to each
TCS (TDDL) instance.
