Github user tzulitai commented on the issue:

    Regarding some of your notes:
    - The exposure of the checkpoint lock through `SourceContext` is meant for sources to
atomically update their state (e.x. Kafka offsets) with record emitting, with regards to Flink's
checkpointing mechanics for exactly once.
    - I don't think there has been any solid discussion on migrating to Java 8 yet.

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.
