Something I would consider for removal with NiFi 2.0 is the concept of

> 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.
