getServiceReferences(...) returns service references guaranteed to be
classloader compatible with your bundle
ie. you should not get a ClassCastException when you cast the service
instance to the appropriate class/interface.
( basically filters the set with isAssignableTo... )
getAllServiceReferences(...) returns all service references matching the
request, regardless of whether they are
classloader compatible, so you may get ClassCastExceptions if you tried to
actually use the service instance
see the method javadoc (http://www2.osgi.org/javadoc/r4) for the algorithms
used to create each set of references
Kind regards,
