camel cxf-client does not handle errors if there is no output in wsdl

Question

if there is no output in wsdl no error is handled if host is unavailable, if host is available - no CamelHttpResponseCode header wsdl:

    <binding name="NumberConversionSoapBinding" type="tns:NumberConversionSoapType">
        <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
        <operation name="NumberToWords">
            <soap:operation soapAction="" style="document"/>
            <input>
                <soap:body use="literal"/>
            </input>
        </operation>
    </binding>

blueprint route:

    <camelcxf:cxfEndpoint xmlns:camelcxf="http://camel.apache.org/schema/blueprint/cxf" xmlns:service="http://www.dataaccess.com/webservicesserver/"
                          id="numberConversionSoap" address="http://myhost:8088/mockNumberConversionSoapBinding" serviceName="service:NumberConversion"
                          endpointName="service:NumberConversionSoap" wsdlURL="mockNumberConversionSoapBinding.wsdl">

        <camelcxf:properties>
            <entry key="dataFormat" value="PAYLOAD"/>
            <entry key="mtom-enabled" value="false"/>
            <entry key="loggingFeatureEnabled" value="true"/>
        </camelcxf:properties>
    </camelcxf:cxfEndpoint>
...
        <route>
            <from uri="jms:queue:myQueue"/>

            <onException >
                <exception>java.lang.Exception</exception>
                <to uri="direct:ErrorHandler"/>
            </onException>

            <setHeader headerName="operationName">
                <constant>NumberToWords</constant>
            </setHeader>
            <to uri="cxf:bean:numberConversionSoap"/>
            <convertBodyTo type="String"/>
            <to uri="log:resp?showAll=true"/>
        </route>

the only thing I can see if I'm unavailable http://myhost:8088/mockNumberConversionSoapBinding :

Caused by: java.net.ConnectException: Connection timed out: connect

the exception is not raised or caught I don't think this is normal behaviour, is it a bug of the camel-cxf component or the cxf framework? my stack: karaf 4.2.16, camel 2.24.5(camel-cxf), cxf 3.3.10
