[google-appengine] When will we get App Engine Flex on Java 11?

[Tom Harris]

Hi all:

We have a set of microservices written in Java that run on App Engine 
standard, and one that runs in App Engine Flex. Last year, we upgraded all 
the App Engine standard services to run spring boot with Java 11, and all 
are now running fine in production. However, our one App Engine Flex 
service is still stuck on Java 8, waiting for Java 11 support for Flex. 
This service currently runs with Jetty 9 and is using web sockets and 
google cloud pub/sub.

Is support for the App Engine Flex platform with Java 11 planned? If so, 
when? And if not, what is the suggested alternative? We cannot keep running 
things on Java 8 forever, as it has end-of-life for a while now.

Thanks,
Tom Harris
