In regards to what we test:
We run our tests against Java 8 *and *Java 11, with the compilation and
testing being done with the same JDK.
In other words, we don't check whether Flink compiled with JDK 8 runs on
JDK 11, but we currently have no reason to believe that there is a
problem (and some anecdotal evidence to support this).
Some tests are excluded from Java 11; some due to library
incompatibility (e.g., Cassandra), some because our docker images are
still using Java 8 (anything docker-related stuff is _not_ tested for
Java 11, as are Yarn end-to-end tests), and some for currently unknown
reasons (Kafka end-to-end test).
You _should_ be free to use any JDK 11 exclusive APIs within your code,
but we haven't tested it specifically.
You don't have to re-compile Flink; the binary that we will be releasing
should work on both Java 8 and 11.
Do note that we have not done any tests on JDK 12+.

Hi,
Thank you for your answer. Btw it seams that you send the replay only
to my address and not to the mailing list :)
I'm looking forward to try out 1.10-rc then.
Regarding second thing you wrote, that
/"on Java 11, all the tests(including end to end tests) would be run
with Java 11 profile now."/
I'm not sure if I get that fully. You meant that currently Flink
builds are running on java 11?
I was not rebuilding Flink 1.9.1 sources with JDK 11. I just ran 1.9.1
build on JRE 11 locally on my machine and
I also modify Job Cluster Dockerfile to use openjdk:13-jdk-alpine as a
base image instead openjdk:8-jre-alpine.
Are here any users who are currently running Flink on Java 11 or
higher? What are your experiences?

Hi, Krzysztof
Regarding the release-1.10, the community is now focus on this effort.
I believe we will have our first release candidate soon.
Regarding the issue when running Flink on Java 11, all the
tests(including end to end tests) would be run with Java 11 profile
now. If you meet any problem, feel free to open a new JIRA ticket or
ask in user/dev ML.
Best,
Yangze Guo
