OpenJDK remains an Oracle project and all contributors should sign the Oracle Contributor Agreement (OCA). Although, an agreement of this nature exists in some other open source communities. But I feel, hesitant to grant Oracle the following rights : - License any patents bearing on your contributions to Oracle. - Assert that you are legally entitled to grant Oracle these rights. - Oracle have full copyright ownership of all the code in that project.

But all sorts of projects have such requirements, any open source project by Google does. That isn't unique or special to Oracle.
