Soap attachments were dropped on server responses. Attachment can be added on a handler's handleResponse method; however it mysteriously disappeared on the outgoing soap message.

The problem was in the ServiceEndpointInvoker. It overwrote the SOAPMessage in the MessageContext. In this class, the method invokeServiceEndpoint was overwritten by ServiceEndpointInvokerEJB21, which invokes the EJB via the ServiceEndpointInterceptor. This ServiceEndpointInterceptor invokes the EJB and also the handlers; it creates the correct SOAPMessage and sets it in the ContextContext. Unfortunately, it was overwritten later by the ServiceEndpointInvoker.

Fixes are attached.
