[jira] [Commented] (NIFI-10147) Remove Support for Java 8

["Kevin Doran (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/NIFI-10147?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17557038#comment-17557038 ] 

Kevin Doran commented on NIFI-10147:
------------------------------------

Do we want to make a 2.0 development branch in the central code repository? I'm thinking it would be a place that experimental work could begin, to be continually rebased on main, until we are ready to release 2.0, at which point we could push the 2.0 development branch to main. Would this be helpful to start making progress? Would rebases be too complicated to sustain this work?

> Although multiple vendors have planned extended support for Java 8, a number of projects are in the process of deprecating and removing support for Java 8. These projects include the following:
>  - [Jetty 9.4|https://github.com/eclipse/jetty.project/issues/7958]
>  - [Spring 5|https://spring.io/blog/2021/09/02/a-java-17-and-jakarta-ee-9-baseline-for-spring-framework-6]
>  - [OpenSAML 3|https://shibboleth.atlassian.net/wiki/spaces/OSAML/overview]
> Apache NiFi should also remove support for Java 8 in order to maintain active support for various components.
> Removing support for Java 8 requires a new major version release and will also require several build configuration changes including the following:
>  - Updating Maven source and compiler settings
>  - Updating minimum Java build version
>  - Removing optional Maven build profiles
>  - Updating GitHub workflows
> Initial discussion on a migration strategy included a tentative target of the end of calendar year 2022.
> Implementation should not proceed until after a minor release of Apache NiFi 1.17.0.
