Decoupled Endpoint: Setting ReplyTo header

Hi,

I'm trying to set the ReplyTo header in my soap request. This is my code. It doesn't seem to set the header correctly.

@Grapes([
@Grab(group = 'com.github.rahulsom', module = 'ihe-iti', version = '0.3'),
@Grab(group = 'org.apache.cxf', module = 'cxf-rt-ws-addr', version = '2.6.7'),
])

import ihe.iti.xds_b._2007.RespondingGatewayQueryService
import oasis.names.tc.ebxml_regrep.xsd.query._3.AdhocQueryRequest
import oasis.names.tc.ebxml_regrep.xsd.query._3.ResponseOptionType
import oasis.names.tc.ebxml_regrep.xsd.rim._3.AdhocQueryType
import oasis.names.tc.ebxml_regrep.xsd.rim._3.SlotType1
import oasis.names.tc.ebxml_regrep.xsd.rim._3.ValueListType
import org.apache.cxf.ws.addressing.WSAContextUtils

import javax.xml.ws.BindingProvider
import javax.xml.ws.soap.AddressingFeature

RespondingGatewayQueryService theService = new RespondingGatewayQueryService(new URL('http://localhost:8080/healthdock/alpine/xca-r-query?wsdl'))

def thePort = theService.getRespondingGatewayQueryPortSoap12(new AddressingFeature(true, true))
BindingProvider bp = thePort
bp.requestContext[BindingProvider.ENDPOINT_ADDRESS_PROPERTY] = 'http://localhost:8080/healthdock/alpine/xca-r-query'
bp.requestContext[WSAContextUtils.REPLYTO_PROPERTY] = 'http://localhost:9090/decoupled_endpoint'

def query = new AdhocQueryRequest()
.withAdhocQuery(new AdhocQueryType()
.withId('123')
.withSlot(
new SlotType1(name: '$XDSDocumentEntryPatientId', valueList: new ValueListType(value: ['123^^^&1.2.3.4&ISO'])),
new SlotType1(
name: '$XDSDocumentEntryStatus',
valueList: new ValueListType(value: [
'urn:oasis:names:tc:ebxml-regrep:StatusType:Approved',
]))

.withResponseOption(new ResponseOptionType()
.withReturnType('LeafClass')
.withReturnComposedObjects(true)

thePort.respondingGatewayCrossGatewayQuery(query)
This is what I receive at the server

Any hints as to what I'm doing wrong? Oh, and my code is in groovy.
