Release 0.22
DOSGi version upgraded to 1.5.0. It solves ConcurrentModificationException's executing OpenNaaS.
Solve OPENNAAS-1108.

The error was in org.opennaas.extensions.router.capability.vrrp.VRRPCapability.java

updateVRRPVirtualIPAddress method crafted a VRRPProtocolEndpoint param object (not used) but used the original VRRPProtocolEndpoint vrrpProtocolEndpoint to call the action.
Using param to call the action solves the issue by avoiding the error.
