When running the build on JDK9 we currently disable some modules because of third party tools not working fine yet.

One of the disabled modules is <module>integrationtest/osgi/karaf-it</module> as the current version we use of Apache Karaf (and possibly PAX-EXAM?) are not booting when running the build with JDK9.

N.B. the current pom.xml triggers a profile which will skip this module automatically when running with JDK9, so to test this one will have to amend the build files first.
