[omniORB] Error creating JTC Thread inside OmniORB thread??

[Stein-Ole]

Hello,

I'm currently attempting to port some code from Orbacus to OmniORB, but I
keep coming up against a problem whenever I try to create a JTC thread
inside what I think is an OmniORB thread. Below is a typical example.

One of the processes I have tried to port to OmniORB core dumps when 
running it. When running dbx, I get the following output :-

(I realise how meaningful these messages are, so I've highlighted the 
relevant parts in red)

Below is a portion of the UIServant header file that the ProcessListener 
is a JTCThread :-

   class ProcessListener : public JTCThread,
                           public ModelListener {
   public:
       static const int maxEventsQueued = 20;
       ProcessListener(UIServant* servant)
               : ModelListener(maxEventsQueued), servant_(servant) {}
       virtual void run();
       void terminate();
   private:
       UIServant* servant_;
   };
   typedef JTCHandleT<ProcessListener> ProcessListenerHandle;
   friend class ProcessListener;

I guess the question is have anyone seen this problem and if so do you 
have a
workaround?

I only see this problem when a create a JTCThread. I can use mutexes 
without a problem.
