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
