javadoc error on mvn install

[eis]

Tried to install this using "mvn clean install". First I encountered the issue described in #196 and after that, I get

Skipping using -Dmaven.javadoc.skip=true doesn't help either, as then it fails with missing javadocs.

Apparently JDK 8 is not yet supported. Changed to JDK 7 and it works. As we're using enforcer-plugin for maven version, we should add a similar rule for JDK 8.

It might be the general issue of javadoc tool in JDK 8 being more strict, see http://mail-archives.apache.org/mod_mbox/hadoop-common-issues/201311.mbox/%3CJIRA.12681661.1385586762252.48109.1385753855233@arcas%3E and http://stackoverflow.com/questions/15886209/maven-is-not-working-in-java-8-when-javadoc-tags-are-incomplete. However, once I got the build to work once by using JDK 7, I seem to be unable to reproduce the problem anymore so I cannot verify if the SO solution will work. Also, it would need to be introduced in a way it doesn't impact building on older JDKs.

not sure if this is the best solution but adding

<configuration><additionalparam>-Xdoclint:none</additionalparam></configuration>

to maven-javadoc-plugin gets it building successfully
