Description

Right now, we are building and running Lens on only on java8 and higher versions. We are not able to generate javadocs with java8 due to some new rules/constraints on javadocs.

Creating this jira for fixing the javadoc errors and warnings. We should fail the build( <failOnError> ) in case of any errors while generating javadocs.
