Ok, that's working fine now:
zapi.getService(PrincipalAnnotationServiceName)

for to use in a adapter where adapts local or global utilities.

The method getService(PrincipalAnnotationServiceName) in a adapter returns
the principal annotation service on global utilities form a service manager
above. Then the principal annotation service exist as a local service and is
above the service manager where the adapter adapts the global utility. And
there was no easy way for to make shure the adapter could be used for global
and local utilities, becaus of their different lookup of the local principal
annotation servcice from the global or local context of the utility.
