Good idea. So it's failing on:
TCN_LOAD_CLASS(env, jFinfo_class, TCN_FINFO_CLASS, JNI_ERR);
And I need to define this in the JNI configuration, much like it's done for
Java reflection and dynamic class loading. Only difference I haven't really
been using it yet. The classes are traced but the configure tool which
converts the trace into the config does not work properly [yet].
