Tomee with spring managed cxf jaxrs rest services not working - spring

Question

I have an application that uses JAX-RS annotations and spring CDI.
It works fine in tomcat (apache-tomcat-7.0.57), but in Tomee-plus (apache-tomee-plus-1.7.2) it won't run with the error:
Invalid NamespaceHandler class [org.apache.cxf.jaxrs.spring.NamespaceHandler] for namespace [http://cxf.apache.org/jaxrs]
In the tomcat version I include the cxf-rt-frontend-jaxrs and cxf-rt-transports-http jars in the .war file, whereas for the Tomee-plus version I mark those jars as provided, as tomee-plus has those already.
This is my pom (just the dependencies cause that's about all there is (this is the tomee-plus version with scope=provided):
<properties>
<spring.version>4.1.6.RELEASE</spring.version>
<cxf.version>2.6.16</cxf.version>
</properties>

This is my REST service
#Component
#Path("/user")
public class UserService {
#GET
#Path("get")
public String get(){
return "hello";
}
}
When running in tomcat all works fine, but in tomee-plus I get the following exception (note that in tomee-plus the cxf jars are provided in the tomee lib dir and so are not included in the .war file)

The root cause is reported as a class not found for org.springframework.beans.factory.xml.NamespaceHandlerSupport, but I think this is misleading.
When tracing through the code I found that the error was caused by the class 'org.apache.cxf.jaxrs.spring.NamespaceHandler' not being able to be loaded because of a LinkageError.
The reason I need this is because I am trying to integrate a 3rd party lib that uses cfx and spring into an existing app.
Is this error related to class loading problems in tomee-plus, since cxf is in the tomee lib?
If I move the spring jars into the tomee-plus lib directory, it works fine, however, we want to avoid having to modify tomee at all.
Does anyone know how to get around this so that a spring/cfx app can be run in tomee-plus?
