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).
> Javadocs build fails with Java 8 update 121

> Key: LUCENE-7651
> URL: https://issues.apache.org/jira/browse/LUCENE-7651
> Project: Lucene - Core
> Issue Type: Bug
> Components: general/javadocs
> Affects Versions: 6.4
> Environment: Java 8 update 121
> Reporter: Uwe Schindler
> Assignee: Uwe Schindler
> Priority: Critical
> Labels: Java8
>
> 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).
