ArquillianCoreTest.testInitialProfiles() fails

It fails because the structure of https://raw.github.com/forge/plugin-arquillian/master/src/main/resources/containers.json has been changed (the containerType field has been replaced with container_type).
See http://jenkins.mw.lab.eng.bos.redhat.com/hudson/job/jbosstools-arquillian_41/95/changes

The issue has already been fixed in the master branch.
