Hi Thierry,

I know the line gets blurry as myself and others will sometimes answer 
Oracle JDK specific questions here, but this is an OpenJDK specific list 
and why Mario answers from that POV.

As a consumer of Oracle JDK/JRE binaries, the best place to send 
feedback is

As per the mentioned release notes, we plan to remove it in an upcoming 
release, but it's still TBD.  As per our Support Road Map page[1], the 
Oracle JDK 8 deployment is the only supported and recommended deployment 
stack at this time.
