------------------------------------

             Summary: Compatibility module to support old versions of projects at runtime
                 Key: CAY-2339
                 URL: https://issues.apache.org/jira/browse/CAY-2339
             Project: Cayenne
          Issue Type: Sub-task
          Components: Core Library
    Affects Versions: 4.1.M1
            Reporter: Nikita Timofeev
            Assignee: Nikita Timofeev
             Fix For: 4.1.M1


New XML loading fails to load old versions buy default. Though this incompatible behavior
but it is much safer to use by default as it has no side effects that were possible.

However we can create separate module that can perform project upgrade on the fly, so it will
be possible to still use old projects that impossible to upgrade (e.g. it can be part of some
third-party library).
