Uwe Schindler commented on LUCENE-7651:
---------------------------------------
I just checked. The "hack" also works with IBM J9, so I see no problem doing
this. I was afraid that maybe IBM does not have script.js in the Javadoc output.
Nevertheless, this is not risky like the previous hack. If the Javadocs
generator no longer produces script.js or stylesheet.css the Code Prettify
would just no longer work, but not break Javadocs or build.

> 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

>
> 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).
