Wildfly won't play nicely with camel: IllegalArgumentException: Type is not a Component implementation

I'm trying to get apache camel running on wildfly 9.0.2.Final.

Using the guide here, I've downloaded a wildfly bundle WildFly-Camel 3.3.0 and patched my wildfly instance.

My route configuration uses netty-http, like this:

from("netty-http:http://localhost:8459/broker/router.jsp").convertBodyTo(String.class)

So I have added camel-netty-http version 2.16.2 to my project.

However, when I start up, I get the following stack trace:

Caused by: org.apache.camel.ResolveEndpointFailedException: Failed to resolve endpoint: netty-http://http://localhost:

Looking at the camel source here, it seems this exception is thrown when the Component specified is not a org.apache.camel.Component:

if (Component.class.isAssignableFrom(type)) {
        return (Component) context.getInjector().newInstance(type);
    } else {
        throw new IllegalArgumentException("Type is not a Component implementation. Found: " + type.getName());
    }

But it clearly is a Component, and it's the correct version too.

What can I be doing wrong? Is it perhaps picking up the Component class with a different classloader than the one loading the NettyHttpComponent class?

netty-http component is not supported by wildfly-camel. You should use the components they support listed here: https://wildflyext.gitbooks.io/wildfly-camel/content/components/index.html
