Sprint:
Blue Ocean 1.2-beta1

Problem
We started getting NPE whenever browsing the main dashboard or individual maven projects. There seems to be 1 for each Maven project. This started to happen recently when BlueOcean was integrated into left hand side menu. The BlueOcean seems to work in Freestyle or multibranch projects but not in Maven ones.

Reproduction steps

Create a maven job using https://github.com/i386/feedle
Run the job
Browse to the job in Blue Ocean

You should see an error like the one below in the log
