Occational NPE in CamelNamespaceHandler
Hi.
Occationally I get a NPE that seems related to CamelNamespaceHandler
when running under Java 7. Switching back to Java 6 I don't seem to
get this problem.
The problem seems very similar to the one from this thread
http://camel.465427.n5.nabble.com/Occasional-CamelNamespaceHandler-exception-when-running-with-Spring-DM-1-2-tt476984.html
, however as the thread is quite old, I would like to know if anyone
else has experienced this, and how to avoid it.
My setup is a Grails 1.3.7 Application, using Camel 2.8.0, jdk1.7.0
I have a camelContext configured in the spring resources.xml like this:
<camel:camelContext id="camel">
<camel:routeBuilder ref="eventReceiverRouteBuilder" />
</camel:camelContext>
I also get the same error if I try to configure it in resources.groovy
like this:
xmlns camel: 'http://camel.apache.org/schema/spring'
camel{
camelContext(id:"camel"){
routeBuilder(ref:"eventReceiverRouteBuilder")
}
}

Maybe a matrix build job in jenkins w/ jdk 6 and 7 would be a good thing?

Just to clarify. Spring DM was just referred to in the old post.
My environment is Grails, but I've got the problem both running grails
run-app, and packaged as a war file deployed to jetty and glassfish.

Hi
Thanks for the heads up. We have no official support for JDK7 with Camel.
This is something we will work on in one of the next releases. But
JDK7 has just been released.
Likewise the issue could also steam from Spring-DM and thus harder to
resolve. But thanks for reporting your observations.
