Description

I use apache-camel-1.4.0 and apache-cxf-2.1.1 in my application.
My application is a web service application.Which receive a soap header + soap body, and then response a soap header + soap body.

I use WSDLToJava tool to create the java code from wsdl, it creates an interface for me as follow:
@WebService(targetNamespace = "http://com.aspire/", name = "Service")
@XmlSeeAlso(

{aspire.com.xsd.ObjectFactory.class}

)
@SOAPBinding(parameterStyle = SOAPBinding.ParameterStyle.BARE)
public interface Service

{ @SOAPBinding(parameterStyle = SOAPBinding.ParameterStyle.BARE) @WebMethod public void serviceReq( @WebParam(partName = "request", name = "serviceReq", targetNamespace = "http://com.aspire/xsd") aspire.com.xsd.ServiceReq request, @WebParam(partName = "requestHeader", name = "serviceHeader", targetNamespace = "http://com.aspire/xsd", header = true) aspire.com.xsd.ServiceHeader requestHeader, @WebParam(partName = "response", mode = WebParam.Mode.OUT, name = "serviceResponse", targetNamespace = "http://com.aspire/xsd") javax.xml.ws.Holder<aspire.com.xsd.ServiceResponse> response, @WebParam(partName = "responseHeader", mode = WebParam.Mode.OUT, name = "serviceHeader", targetNamespace = "http://com.aspire/xsd", header = true) javax.xml.ws.Holder<aspire.com.xsd.ServiceHeader> responseHeader ); }

Then, I implement the routing rules in the xml file. In my processor, I only need set response body and response header.I have traced the exchange object of the processor, the exchange.out element is null, and the exchange.in element is a CxfMessage object. The exchange.in.body element is a MessageContentList object: Object[0] is ServiceReq, Object[1] is ServiceHeader, Object[2] is a Holder<T>, Object[3] is a Holder<T>.

So i put response body into Object[2], and put response header into Object[3]:
org.apache.camel.Message in = exchange.getIn();
List inBody = (List) in.getBody();
Holder holderBody = (Holder)inBody.get(2);
holderBody .value = body;// body is a ServiceResponse object
Holder holderHeader = (Holder)inBody.get(3);
holderHeader .value = header;//header is a ServiceHeader object

But, when I run the application, I got an Exception:java.lang.OutOfMemoryError: Java heap space.
I debuged into program, there is an Infinite Loop occured at the
org.apache.cxf.jaxws.interceptors.HolderOutInterceptor(72):
for (int x = 0; x < inObjects.size(); x++) {
Object o = inObjects.get;
if (o instanceof Holder)

{ outObjects.set(x + 1, o); }

}
I have traced and found: inObjects == outObjects is true, which leads to an Infinite Loop.
