Well.... I didn't see this one coming.... I decided to google CamelNameSpaceHandler NullPointerException. There were a bunch of reports of this identical failure symptom (working periodically / failing most of the time) occurring back in late 2011 thru mid 2012. Lots of discussion about it. But the bottom line? It's a bug in Java 7. The general consensus was that the right solution is to go back to Java 6. I had an old copy of Java 6 still installed on my server. So I pointed back to it. At this point, it appears that the problem has gone away. I'm assuming (hoping) that the problem was fixed in a later version of Java 7 and hopefully I won't have to stay on Java 6 forever. But until I get time to download and install the latest Java 7 version. I'm just going to stay on 6.

Looking in spring-server.xml which appears to be the file spring is working through during this, the relevant definitions are:

    <!-- Mailet Container -->
<import resource="classpath:META-INF/spring/mailetcontainer-context.xml"/>

    <!-- Camel Context -->
    <camel:camelContext id="jamesCamelContext" trace="false">
<camel:jmxAgent id="agent" disabled="false" createConnector="false" serviceUrlPath="/jmxrmi/jamescamel"/>
    </camel:camelContext>

    <!-- DNS Service -->
    <import resource="classpath:META-INF/spring/dns-context.xml"/>

The camel:jmxAgent processing is where the failure is occurring. What is this defining?
