[jira] [Commented] (MJAVADOC-387) Handle JDK8 -Xdoclint

Stian Soiland-Reyes commented on MJAVADOC-387:
----------------------------------------------

Any progress on this? 

I must agree that it's not very good of Oracle to have added an activated default which must be disabled with a (previously unknown) "nonstandard option".

The use of Maven activation profiles is not a good workaround. So I would go with Tubbs' solution - default is as-is, and a new {{<doclint>whatever</doclint>}} will add {{-Xdoclint:whatever}} without any validation. There can be a special recognition of {{<doclint>none</doclint>}} which means {{-Xdoclint:none}} on JDK 8++ but nothing on JDK 7--. Use of any other {{<doclint>}} in pre-Java 8 should log a warning (not be bluntly passed as -Xdoclint). {{<doclint />}} can be equivalent to {{-Xdoclint}}  - the arbitrarily selected profile built in to the Javadoc distro.

I don't know what the behaviour should be for non-Oracle / non-OpenJDK javadoc which may not hava doclint - but at least with a special option it's possible to fix that generally in the javadoc plugin as opposed to the use of profiles and {{additionalparam}}.

> The Oracle team have added the doclint tool to JDK 8. The tool validates Javadoc as part of a standard Javadoc run. Unfortunately, with the default settings, it rejects many HTML elements that are perfectly acceptable to browsers, and all invalid Javadoc references (@links). This is likely to prove very unpopular with developers.
> Action needed:
> 1) Provide a maven-javadoc-plugin configuration item and property that can control the doclint tool (currently this requires using additionalparam AFAICT).
> 2) Apply the {{-Xdoclint:none}} option by default, so that doclint is opt-in, not opt-out (ie. fix Oracle's messed up default). This will also make it much easier for developers to handle migration to JDK 8.
