Andrus Adamchik commented on CAY-1882:
--------------------------------------
ClassRegistry approach appears too simplistic. I am not even sure how it works
under 3.2 :) E.g. I can't load XML mapping files as DataDomainProvider is not
using AdhocObjectFactory. My little OSGi test project [1] fails even before it
starts loading persistent entities [2]. So I opened a separate Jira CAY-1887 to
deal with Cayenne class loading in a more systematic fashion.
