You have two choices:
a) You can use Habitat object to unregister/register yourself HK2 service.
b) You could also expose your service as OSGi service with a
component.name service property (set this to the name that you use while
using looking up the HK2 service) and let it be automatically
added/removed to/from the HK2 service registry as a named HK2 service.
