Subject [jira] [Commented] (HADOOP-15304) [JDK10] Migrate from com.sun.tools.doclets to the replacement
Date Wed, 28 Mar 2018 20:38:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-15304?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16418072#comment-16418072
] 

Akira Ajisaka commented on HADOOP-15304:
----------------------------------------

I'd like to simply exclude this package when compiling with Java 10 or upper because

* Current implementation is using a lot of reflections, so it doesn't work for new doclet
API.
* Jigsaw was introduced in Java 9 and new doclet API support this, so ideally we should use
the Jigsaw feature to export only {{@Public}} elements to other projects and create javadoc
by new {{--show-packages=exported}} option instead of relying on the annotations.
