When we build javadocs of nutch using the command : "ant javadoc"
we get a handful of errors and the build fails. This is because up to JDK 7, the Javadoc tool was pretty lenient. With JDK 8, a new part has been added to Javadoc called doclint and it changes that friendly behaviour. Warnings turned out into errors with JDK 8.
