Collection properties of data objects should return empty collection instead of 
null

                 Key: CMIS-136
                 URL: https://issues.apache.org/jira/browse/CMIS-136
             Project: Chemistry
          Issue Type: Wish
          Components: opencmis-provider
            Reporter: Stephan Klevenz
            Priority: Minor


This is a wish. Some data objects in org.apache.opencmis.commons return null 
for collection properties in case of the collection is empty. I would like to 
suggest that collection return always empty list rather than null. Null leads 
to unnecessary checks everywhere and causes a lot of NPE. It is simply error 
prone.

What do you think?
