Daniel Kulp resolved CXF-5496.
------------------------------

       Resolution: Won't Fix
    Fix Version/s: Invalid
         Assignee: Daniel Kulp

This is working as designed.   CXF is designed to stream as much stuff as possible and not pull things off the stream and cache them someplace locally unless specifically required or requested.   

In this case, the writeTo is consuming the data from the stream as it writes the attachments out.   The SAAJ+JAX-WS specs mandates that the writeTo does that within the SOAPHandler.   

If you need this changed, you can add an interceptor modeled off of:
http://svn.apache.org/repos/asf/cxf/trunk/rt/databinding/jaxb/src/main/java/org/apache/cxf/jaxb/attachment/JAXBAttachmentSchemaValidationHack.java

that would cache the attachments and lock them down, however it's not something we'd do by default due to the performance impact that would cause in the normal cases where that isn't needed.

> In a client I receive SOAP attachments.
> Retrieving them within a SOAPHandler via
> {code}
> context.get(MessageContext.INBOUND_MESSAGE_ATTACHMENTS)
> {code}
> works, but if I first do (for logging purposes)
> {code}
> SOAPMessage soapMessage = context.getMessage();
> ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
> soapMessage.writeTo(outputStream);
> {code}
> and afterwards try to retrieve the SOAP attachments via:
> {code}
> context.get(MessageContext.INBOUND_MESSAGE_ATTACHMENTS)
> {code}
> the DataHandler gives me an empty byte array.
