The post in question: https://openjdk.org/legal/ai
It is 'OpenJDK Interim Policy on Generative AI' and their lawyers are writing the final version, according to this page.
It sounds like a sensible action, given past scars around Java and copyright, plus this is from a big old corp.
That said I personally don't expect that final proposal will end up any better.

How many of these were self-inflicted?
Does it matter?
I guess that depends on whether you think the motivations matter. When it comes to a policy on a hot-button issue that seems like it could easily be enforced selectively, I don't think it's a stretch to be concerned about whether the one who crafts and enforces the policy for a project that's supposed to be open having a track record of being the cause of the issues supposedly that make the policy "sensible".
Intentional rather than self-inflicted.
Not sure how common this understanding of the terms is, but to me, those terms don't seem conflicting.
