Hans, could you provide more detail?

I only see the Javadoc task extend the ConventionTask class from our internal api's

At the moment we are hiding errors in the javadoc. For example if a public class has a javadoc link to a non-public class, we don't get a warning at the moment. This is because the whole Gradle classpath is in the classpath of the Ant javadoc task, not just the classpath of the public API.

As announced on the Gradle blog we are planning to completely migrate issues from JIRA to GitHub.

We intend to prioritize issues that are actionable and impactful while working more closely with the community. Many of our JIRA issues are inactionable or irrelevant. We would like to request your help to ensure we can appropriately prioritize JIRA issues you’ve contributed to.

Please confirm that you still advocate for your JIRA issue before December 10th, 2016 by:

• Checking that your issues contain requisite context, impact, behaviors, and examples as described in our published guidelines.
• Leave a comment on the JIRA issue or open a new GitHub issue confirming that the above is complete.

We look forward to collaborating with you more closely on GitHub. Thank you for your contribution to Gradle!

Thanks again for reporting this issue. We haven't heard back from you after our inquiry from November 15th. We are closing this issue now. Please create an issue on GitHub if you still feel passionate about getting it resolved.
