Where did we land on this? Don't seem to have a clear consensus from thread
discussion.

Even if it is experimental, I feel that it would be best for users if we
treat java 11 bug reports the same as java 8 bug reports; it would be a bad
user experience if a user found out we knew about an issue but wanted to
ignore it in favor of releasing.
If we block the release on JDK11 issues we find, it *seems* to me that

To me there is a big difference. If users report bugs that only happen on
JDK11 then we should treat those as normal bugs found while testing the
release. This stance does not mean that java 11 testing is on-par with our
java 8 testing, it only means we treat reports of issues equality
regardless of JDK version.
stance on found defects for JDK8 as we have for JDK11
Yep, that is what I am asking for, we should have the same stance on found
defects for JDK 8 and JDK 11.

I believe I understand your last comment as "I am ok treating bug reports
on JDK11 the same way as JDK8", if so then we are on the same page. The
other comments about deferring would imply we have a different stance than
we do for JDK8; which I feel is the main gap?

If we block the release on JDK11 issues we find, it *seems* to me that
that's the same as saying "JDK11 is supported" assuming we have the same a)
level of testing and b) stance on found defects for JDK8 as we have for
JDK11. Which I'm totally fine with fwiw.
What in my mental model here ^ doesn't match yours? :) Seems there's some
gap.

Re: [DISCUSS] Revisiting Java 11's experimental status
Posted by David Capwell <dc...@gmail.com>.
My statement was more coming from the fact that if we test on java 8 and
find an issue it is a release blocker, so saying java 11 should be treated
with the same regard as java 8 when it comes to filing/fixing issues; when
it comes to filing and fixing issues, we shouldn't have different stances
on different JVMs. I don't want us to say "java 11 is experimental, so
lets ignore issue X", we will have a hard time getting out of
experimental if we have this stance.
Now, don't get me wrong. If something is very specific to java 11 and we
can reason that the impact to users is near zero, I am fine not marking the
issue as a release blocker. An example is that jvm dtests crash the JVM
because of a race condition with CMS and class unloading, this issue
shouldn't block the release but we should still find a way to make it
stable (changed flags when running tests on java 11 to avoid the issue).
With regard to #2, we have a ways to go to get CI on-par but there is
traction already on both fronts. I run the java (not python) suite on java
11 frequently and see that known flaky tests are still flaky on java 11,
though the suite tends to pass with enough retries.

Maybe we let 2 run and see how many issues there are before we call release
blocking?

Re: [DISCUSS] Revisiting Java 11's experimental status
Posted by David Capwell <dc...@gmail.com>.
I would propose the following:
1) leave jdk 11 marked as experimental
2) make sure CI runs jdk 8 and jdk 11 for all builds (circle / jenkins)
3) during 4.0 qualification, issues found on jdk 11 should block the release
This should get us in good shape to potentially be ready to flip the switch
in 4.1 or even 4.0.1; given that not everyone is signing up to test java
11, #3 might not be enough to fully mark stable.
