As before, Oracle's CPU schedule is available here: 
and the support roadmap is available here: 
http://www.oracle.com/technetwork/java/eol-135779.html .

Based on these documents, you can determine which Oracle Java SE 
releases receive a Critical Patch Update on July 16th, 2019.

As with OpenJDK 6, OpenJDK 7 Updates, OpenJDK 8 Updates, OpenJDK 9 and 
OpenJDK 10, the applicable changes in the corresponding Oracle CPU 
release are applied to all Oracle-led OpenJDK update releases as well.

At this point in time, that's not possible to say with confidence for a 
given date six months after JDK 11 GA. I think the phrase 'at least six 
months of updates' has come up in this thread a couple of times already.

We are currently winding down JDK 10 Updates maintenance in the JDK 
Updates Project, per 

At some point in time after JDK 11 is released, a mail like 
will be sent out to the jdk-updates-dev mailing list, outlining Oracle's 
plans for further contributions regarding that particular release.

So in short, if you want to know when Oracle will stop contributing 
changes to JDK 11 updates in OpenJDK, please subscribe to the 
jdk-updates-dev mailing list, and monitor it for updates.
