Crowd contains a number (22 as of 15/10/2015) of broken references in the Javadoc. With Java 8, the Javadoc compiler reports these as errors and we had to disable that check in the pom.xml file. This is not nice because it requires us to overwrite the Javadoc compiler options specified in the base pom.

The references should be fixed and the additional Javadoc parameter (-Xdoclint:-reference) in the pom file removed.
