The problem is that you have activated the servant in the BOA with the
call to _obj_is_ready(). The BOA now owns it, and you must not delete
it yourself. You get rid of the servant by calling its _dispose()
method:

   MyExample* theExample = new MyExample;
   cout << "about to do: dispose theExample;" << endl;
   theExample->_dispose();

That will unregister it from the BOA, and delete it.

The rules were the same with omniORB 2.8, but it was much less strict
about checking such things.

Cheers,

Duncan.
