Re: [che-dev] java development/runtime version

[Nick Boldt <nboldt@xxxxxxxxxx>]

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

11:10:17 Apache Maven 3.5.4 (1edded0938998edf8bf061f1ceb3cfdeccf443fe; 2018-06-17T18:33:14Z)

11:10:17 Maven home: /var/lib/jenkins/tools/hudson.tasks.Maven_MavenInstallation/maven-3.5.4

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]

11:21:07 Caused by: org.apache.maven.plugin.PluginContainerException: An API incompatibility was encountered while executing net.ltgt.gwt.maven:gwt-maven-plugin:1.0-rc-8:package-lib: java.lang.ExceptionInInitializerError: null

https://codeready-workspaces-jenkins.rhev-ci-vms.eng.rdu2.redhat.com/job/eclipse-che_JDK11_master/4/console

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?
