Subject [jira] [Commented] (LUCENE-7651) Javadocs build fails with Java 8 update 121
Date Sun, 22 Jan 2017 09:31:26 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-7651?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15833412#comment-15833412
] 

Uwe Schindler commented on LUCENE-7651:
---------------------------------------

I checked it out, it disallows any {{<script>}}, also externally linked ones in the
{{-bottom}} parameter of Javadocs. This is amajor pain. As adding this special allow-javascript
parameter is brekaing builds with older versions and its hard to detect the exact build version
in Ant, we have 2 options:

- Remove prettify.js
- Inject the prettify code somehow else into the docs (e.g. by copying all script files together
and append them to the javadoc-generated JS file after javadoc succeeds).

> Oracle released the recent Java 8 security update (u121). The Jenkins builds fail with
the following error while building the Javadocs:
> {noformat}
>   [javadoc] Constructing Javadoc information...
>   [javadoc] javadoc: error - Argument for -bottom contains JavaScript.
>   [javadoc] Use --allow-script-in-comments to allow use of JavaScript.
>   [javadoc] 1 error
> {noformat}
> This is caused by the Javascript added to pretty-print code examples. We load this in
the page footer "{{<bottom>}}" parameter.
> Surely, it will be posisble to simply add the mentioned argument, but this will break
builds with earlier Java 8 versions.
> This is nowhere documented, I haven't seen any documentation about this flag nowhere,
so I assume this is a bug in Java. They can't change or add command line parameters in minor
updates of Java 8. I will ask on the OpenJDK mailing lists if this is a bug (maybe accidentally
backported from Java 9).
