If you need to know the old service properties, you will have had to save a copy of them.
You don't need an identity map. Just use the ServiceReference as the key.

Subject: [osgi-dev] properties of service pre modification
Date: Fri, Mar 4, 2016 5:37 PM
Hello,
when a service is modified via ServiceRegistration.setProperties the
documentation tells me that the properties are updated and then
MODIFIED is fired.
If I use a service tracker modifiedService(ref,service) is called with
the new properties in the service reference.
I haven't found an easy way to get the old properties. Is it correct
that I would have to keep a idenditymap based on the service instance to
remember those keys?
Gruss
Bernd
