EDIT

the maven javadoc plugin fails with java 1.8

this occurred firstly in the cdm-vaadin-RLS-FINISH jenkins job an was reproduce-able locally. The maven javadoc plugin reports a lot of warings and errors and in the end it fails (log from local run of mvn javadoc:javadoc -X below).

According to http://stackoverflow.com/questions/15886209/maven-is-not-working-in-java-8-when-javadoc-tags-are-incompletemvn a interim solution is to disable doclint for jdk1.8, much more recommendet however is fixing the javadoc problems in the code. ---> #6241
