Javadoc

Representation of an active session with a COM server. All interface references being given out by the framework for a particular COM server are maintained by the session and an IJIComObject is associated with a single session only. Sessions are also responsible for the clean up once the system shuts down or IJIComObject go out of reference scope.

Please make sure that you call #destroySession(JISession) after you are done using the session. This will ensure that any open sockets to COM server are closed.
