> I got the following helper function which used to work in older SMX 3 and 4 versions (latest known of SMX4 is 28th of january?).
> Today in the morning I built the latest trunk and the function doesn't work any longer.

> {code}
> I tried to extend this function that in case there is no such service registered, I call the method context.getEndpoints(null) to retrieve all registered
> endpoints (like API Doc says) but it ends up in a NPE which is not JBI compliant.
