          Issue Type: Bug
      Security Level: Public (Everyone can see)
            Reporter: Trong Tran


We can't monitor eXo Platform health in a clean way because if we invoke eXo MBeans during GateIn portal startup, we have dozens of the following NPE which pollute the logs:

*MBeans which seem to cause this problem :*
- exo:portal=portal,repository=\*,workspace=system,cache-type=JCR_CACHE,jmx-resource=CacheMgmtInterceptor
- exo:portal=portal,repository=\*,workspace=system,cache-type=LOCK_CACHE,jmx-resource=CacheMgmtInterceptor
- exo:portal=portal,repository=*,service=SessionRegistry
- exo:portal=portal,repository=\*,workspace=\*,service=Cache
- exo:portal=portal,repository=\*,workspace=\*,service=lockmanager
- exo:portal=portal,service=cache,name=*

*How to reproduce :*
- unzip eXo Platform 4.0.x (or 4.1-M1) tomcat distribution (Community or Express or Enterprise)
- copy the jmxtrans-addon.war war in <PLATFORM_DIR>/webapps/ directory
- start your portal and watch the starup logs
