> When an endpoint is added between a cxf router and a cxf service endpoint the message exchange is interrupted by a NullPointerException.
> Example code:
> -----JAVA-BEGIN----------------------------------------------------------
> //This code works
> from(StringUtils.join(cxfRouterURI)).to(StringUtils.join(cxfServiceURI)); 
> // This code crashes (same problem with seda and log endpoints)
> String anyEndpoint = "activemq:someQueue";
> -----JAVA-END----------------------------------------------------------
>    
> from(StringUtils.join(cxfRouterURI)).to(anyEndpoint).to(StringUtils.join(cxfServiceURI));
