I'm seeing a NPE from MessengerTests since rev 1460174 whilst running
the proton-j maven profile (mvn test -Pproton-j).
It seems new test testDefaultRoute causes a NPE, and then the
following MessengerTests fail with .java.net.BindException: Address
already in use.
The misleading commit message did mean I wasted time looking elsewhere
before homing in on this commit.
