URL: https://github.com/apache/hadoop/pull/8038#issuecomment-3708633935
> given trunk is now java17+ only, do we need to have a java17 source tree
and profile?
>
> We can just delete all java8 code and put this in its place. I would
support this as it keeps the codebase cleaner
@sjlee Apologies for the late reply. The situation is consistent with
@pan3793 feedback. We will completely discontinue support for JDK8 on the trunk
and transition to JDK17 in the future. jdiff is a feature we need to support on
JDK17, as it involves the final jdiff comparison XML file for the release, such
as `Apache_Hadoop_HDFS_3.2.0.xml`. The removal of jdiff support on JDK8 was
also the result of a discussion with Steve.
If there are any new issues, feel free to provide feedback here anytime.

> Issue Type: Sub-task

> JDiff is a tool used to generate Java API documentation and display
> differences between Java classes, primarily for detecting changes in Java API
> across versions. However, JDiff does not support JDK 9 and above, and there
> are no plans for further updates.
> Maven version: JDiff 1.0.9
> https://mvnrepository.com/artifact/jdiff/jdiff/1.0.9
> Official website: JDiff
> https://jdiff.sourceforge.net/
> During JDK 11 support, the changes in HADOOP-15304 allowed the project to
> compile successfully but skipped JDiff. However, generating the JDiff XML is
> still an essential step in the release process.
> To release Hadoop for JDK 11 and above, we need a tool similar to JDiff to
> handle API comparison and detect version changes.
