This annotation (on Class or Interface) is a marker for context objects on which any change of
 profile assignment ensures that there is no indexed object (neither the given object nor any other object in the whole application)
 that is affected in its own 
read access computing.
 
 
Be careful. Being an object not indexed in Solr does 
not mean that
 it is uninfluential on any other indexed object (it can have influence through
 
RightContextConvertor or 
AccessController).
 
 
This is a way to avoid an expensive and useless 
Solr AclCache reload
 in some cases.
