> When trying to delete an endpoint refered by a sequence, no error messages
> are given. Below is what actually happens when you try to invoke such a
> sequence which refers a non-existing endpoint
> 1. Create an endpoint
> 2. Create a sequence with a reference to the above created endpoint
> 3. Send a request to the above endpoint and the results will be retrieved
> successfully
> 4. Now remove the endpoint from the system and try to send the request once
> more
> 5. You will get a Null pointer exception
