Hi Sean,
Yes, I had a look at the Contributing docs at the OpenJDK site
before. I also signed the OCA.
Best regards,
Karl

Hi Karl,
The OpenJDK Developer’s Guide includes a helpful section on
Contributing to an OpenJDK Project [1]. I suggest you read
through that if you have not already. In particular, have you
signed the OCA? I don’t want to review your code/contribution
until that is done.
For this particular contribution, I don’t think there has
been enough discussion and evaluation from members of the
Security project. This would be a fairly major contribution.
Keep in mind that a contribution doesn’t mean the work ends
there. There would need to be documentation, tests, and
ongoing support for the foreseeable future. We need to think
about these aspects every time we add a new feature, so there
needs to be a strong motivation for doing it.
Thanks,
Sean
