> This error seems to appear only at startup because The specified MBean in
> that moment (startup) does not exist in the repository.
> Eik after 25 second try to reload data without problem.
> The improvement that i think to be done, in IMHO, are
> * Improve Job that load service and bundle Data
> * Improve exception handling
> * Make configurable polling frequency
