Alessandro Presta commented on GIRAPH-259:
------------------------------------------

This is the relevant error:

{code}[ERROR] /home/jenkins/jenkins-slave/workspace/Giraph-trunk-Commit/trunk/target/munged/main/org/apache/giraph/graph/Vertex.java:[326,26]

Newer versions of the JDK are a bit smarter at inferring template arguments, but not the one
we have on Jenkins, hence we should always specify them. Fixed now.
