[STORM-3834] Fix ERROR and warnings creating java docs

Storm release steps require creating javadocs using the following command:

mvn javadoc:aggregate -DreportOutputDirectory=./docs/ -DdestDir=javadocs -Dnotimestamp=true -pl '!storm-shaded-deps

see: https://github.com/apache/storm-site/blob/asf-site/README.md

storm-site project is referred in https://github.com/apache/storm/blob/master/RELEASING.md

The maven command runs to completion, but had some ERROR and Warnings that should be fixed.

Start by reviewing the javadoc command in the issue and the release guidance in README.md and RELEASING.md. Run the documented Maven command, identify the reported ERROR and warning output, and verify that the release javadoc generation completes without those diagnostics.
