-------------------------------------
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}}
