set-jaxb-validation-event-handler config is not working

Question

My client is sending an incorrect message (we are migrating from Weblogic10 to Tomee 8.0.15. The first one was more permissive with incorrect xml's acording with de wsdl), so I have been trying to avoid the error

Unmarshalling Error: element unexpeted (URI:"", local:"foo"). Expected elements are &lt ...

So I concluded that adding the following config in openjb-jar.xml (as appear here)

<?xml version="1.0" encoding="UTF-8"?>
<openejb-jar>
    <ejb-deployment ejb-name="MyService">
        <properties>
            cxf.jaxws.properties = MyServiceProperties
        </properties>
    </ejb-deployment>

And this resources.xml

<?xml version="1.0" encoding="UTF-8"?>
<resources>
    <Service id="MyServiceProperties" class-name="java.util.Properties">
        set-jaxb-validation-event-handler = false
        schema-validation-enabled = false
    </Service>
</resources>

or this annotation in the definition of my WebService class

@EndpointProperties({ 
    @EndpointProperty(key = "set-jaxb-validation-event-handler", value = "false")
})

@WebService(name="MyService",targetNamespace="http://my.namespace/MyService" )
public class MyService {
...
}

should avoid the problem.

I'm deploying this services in Tomee 8.0.15, using JAX-WS and Apache CXF.

Any clue why this is not working? I expect that the error of unmarshalling not appear any more.
