That's really beside the point.  What went wrong, IMO, was that
breaking changes were committed but the release was still made even
though it was broken.  That is very unusual in open source projects.
I don't think I've ever seen it happen before.

If Oracle had needed an immediate security release they could have
tagged and released with their own tag, but waited for an ack response
from everyone else using the tree for the final GA release.  IMO,
that is the job of the release manager.

To be clear, I understand the breaking the release was not
deliberately hostile.
