It’s not that we’re not looking, but there is simply too much work for us (the small Hibernate team).
Some community members try to pick up Jira tickets and create a PR with a fix for the problem, usually for stuff they care about themselves. After all, this is an open source project.
If you are a Red Hat or IBM customer, you might be able to request a support ticket to be created for these issues. Then we could prioritize your requests, but until then, you will have to wait until someone from the community picks it up or we (the Hibernate team) find time to investigate.
