Github user PramodSSImmaneni commented on the pull request:

    I rebased it but I am having some second thoughts about a different interface based on
the japicmp discussion that @chandnisingh sent earlier.
    What do you guys think about relaxing the backwards compatibility restriction in the following
way in cases where an "optional" callback needs to be added. We ensure that an app compiled
against an older version still *runs* by doing runtime checks or with error handling even
though the app will *not compile* against the new version without changes. When we are going
to a new major version then we can remove those runtime checks.
    This may be a scenario we might see a few times in future and using a different interface
each time might just make this a little problematic. I was planning to look at this over the
weekend and in course see if I would need to implement a small utility for the runtime checks
that can be reused in the future.
    Let me know if you think we should be having an email discussion on apex-dev about this
rather than this JIRA. 

If your project is set up for it, you can reply to this email and have your
reply appear on GitHub as well. If your project does not have this feature
enabled and wishes so, or if the feature is enabled but not working, please
contact infrastructure at infrastructure@apache.org or file a JIRA ticket
with INFRA.
