Re: [che-dev] java development/runtime version
Hello, devs.
On yesterday's community call I didn't receive any notifications about blockers that can prevent us from moving forward.
Now we have the first green lights on PRs.
I would like to start merging it next Monday, Jun 15.
Please let me know if you see any problems.

Hello, devs. 

We are getting closer to java 11.
I have one additional news. 
During testing alpine based image I've noticed quite a few TLS exceptions
that force me to get back to openjdk:11-jre-slim based image 
which doesn't have that problem https://github.com/eclipse/che/pull/16649#issuecomment-626664906.
If you know how to fix that or think that this is an inappropriate move please let me know.

Hello.

I would like to propose a plan on how we can move forward with this topic.

At this moment I know about such a list of required changes.
https://github.com/eclipse/che-parent/pull/165
https://github.com/eclipse/che/pull/16649
https://github.com/eclipse/che-dashboard/pull/21
https://github.com/eclipse/che-workspace-loader/pull/16
https://github.com/eclipse/che-operator/pull/224

Merging them all at once I think can be potentially risky.
That is why I want to propose to do that in several steps.

1. 7.13 Merge change that is compatible with java 8. That is
   - https://github.com/eclipse/che-operator/pull/224
   - Plugins updates from https://github.com/eclipse/che-parent/pull/165
   - etc?
2. 7.14 Stabilization release.
3. 7.15 Merge all remainings.

We proposed to wait the release of Che 7 before doing this change as this is not on the critical path of the Che 7 release.

Thanks!

Ok. Make sense. Let's divide this question on two.
1. How to build on Java 11
2. Can we run on Java 11.

I'm more interested in 2. Because if answer - NO, first one doesn't make sense.
@Nick Boldt Do you see any issues in 2?

I tried building Che w/ OpenJDK 11ea28...

11:10:17 Java version: 11, vendor: Oracle Corporation, runtime: /qa/tools/opt/x86_64/openjdk11_ea28

... and it failed spectacularly:

11:21:07 [INFO] Che Core :: Commons :: GWT Logger .................. FAILURE [ 2.758 s]

Perhaps we need to move to the JDK 11.0.1 and Maven 3.6?

Hello
I would like to initiate discussing around development/runtime version of java that we use to build and run Che. (workspace agent and workspace server).

Idea is to bump version to the latest LTS Java 11 (18.9^ LTS)  [1]

Does anybody have any comments or concerns?
