ActiveMQ 5.9.1 and Camel HTTP component

[Peter Hicks]

All,

I am not sure if this is an ApacheMQ or a Camel question, but I'm 
experiencing the following issue in AMQ, so it's probably a good place 
to start.

There are several web servers I need to retrieve a single XML file from, 
every 30 seconds.  I want to publish this XML data on a topic for 
distribution to other systems, and it's been suggested I use Camel to do 
this.

Under a <camelContext>, I have the following:

    <route>
      <description>Feed 1</description>
      <from 
uri="timer://feed1timer?fixedRate=true&amp;delay=0&amp;period=30000"/>
      <to uri="http://www.example.com/feed1.xml"/>
      <to uri="activemq:topic:FEED1"/>
    </route>

When I start ActiveMQ, the broker begins to start, but then shuts down 
immediately after the following debug (not error, seemingly) message is 
output:

    2014-05-10 00:35:48,101 | DEBUG | Found component: http in 
registry: null | org.apache.camel.impl.DefaultComponentResolver | main

If I remove the HTTP line from the route, the broker starts successfully 
and sends blank messages on to the topic - from this, it seems that it's 
just the HTTP component that's failing to load.

This is the first time I've started to use Camel for this kind of 
activity - can anyone help out with where I might be going wrong? This 
is on an Ubuntu 14.04 machine with a clean install of ActiveMQ 5.9.1 
under Java 1.8.0_05.
