> My problem is that I've specified a broker name with space in it  "Slave Broker". So
I the new URI() here throw a URISyntaxException that was badly absorb. And this leads to a
null pointer at line:159 of TransportFactory.java.
>    String scheme = location.getScheme(); when location is null du to the previous exception.
> The link between the error and the cause was not clear at the first sigth. 
> A precondition on the setBrokerName could do the job.
