Oracle recently released WebLogic 12c. I have had a lot of customers ask about running ECM products and ADF on the newly released WebLogic Application server. We talked with Oracle and basically the current releases of 188.8.131.52 ECM Products and ADF are not certified for WebLogic Application Server 12c. Also, it does not look like 184.108.40.206 will be certified either.
In short, 12c looks neat and there looks to be a lot of new features but those toys are not currently part of our playground.
