CHEN Zhongpu commented on FLINK-30501:
--------------------------------------
Plz have a look at the answer of my SO answer. The remove of “Java 8” in
doc is intentional, and it is to encourage users to switch to Java 11
before Flink really discards Java 8 in code.

> Key: FLINK-30501
> URL: https://issues.apache.org/jira/browse/FLINK-30501
> Project: Flink
> Issue Type: Improvement
> Components: Build System / CI
> Reporter: Dong Lin
> Assignee: Dong Lin
> Priority: Major
> Labels: pull-request-available
>
> Flink 1.15 and later versions require at least Java 11 to build from sources
> [1], whereas the pom.xml specifies the source/target is 1.8.
> This is inconsistent. We update our doc to mention that Java 8 is deprecated
> instead of saying that Java 11 is required.
> The statement "Fink requires at least Java 11 to build" was added in
> https://issues.apache.org/jira/browse/FLINK-25247. However the JIRA title
> only says "Inform users about deprecation". And the PR was not approved by
> any committer other than the PR author.
