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.
