Thanks for your detailed reply. I now get a bigger picture of what is
going on, and it seems to me that it has nothing to do with
GMail-as-a-client or @oracle as sender.

What seems to be happening is that GMail's MX is not trusting 100%
email originating on the openjdk list...

And that DOES seem to be on-topic for this list and a cause for
concern for whoever admins the openJDK list and java.net
infrastructure (wasn't that Kenai? wasn't that supposed to be shut
down by now?).

Since I know nothing ab SPF spam countermeasures, I think someone from
Java.net infrastructure would be the one who should comment...

So, thanks for reporting this.. and the clarifying follow-up....
