["Laurent Goujon (JIRA)" <ji...@apache.org>]

Laurent Goujon created DRILL-4547:
-------------------------------------

             Summary: Javadoc fails with Java8
                 Key: DRILL-4547
                 URL: https://issues.apache.org/jira/browse/DRILL-4547
             Project: Apache Drill
          Issue Type: Bug
          Components: Tools, Build & Test
    Affects Versions: 1.6.0
            Reporter: Laurent Goujon


Javadoc cannot be generated when using Java8 (likely because the parser is now more strict).

Here's an example of issues when trying to generate javadocs in module {{drill-fmpp-maven-plugin}}
