Yan Min Sheng commented on CXF-4772:
------------------------------------
Well, the problem here is after call DataHandler.writeTo first in application,
img.writeTo(fos); //DelegatingStream to handle this, it will get the binary
content
imgout.getImage().add(img);
fos.close();// it will close the DelegatingStream, i.e, the
MimeBodyPartInputStream will be closed.
After that, when the server side return the ImageDepot to client, the
AttachmentOutInterceptor will be called, and
AttachmentDataStore.getInputStream() will return the same
DelegatingInputStream. Here, the problem is the MimeBodyPartInputStream can
not handle the read request.

> Key: CXF-4772
> URL: https://issues.apache.org/jira/browse/CXF-4772
> Project: CXF
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.6.2
> Reporter: Yan Min Sheng
> Priority: Critical

>
> When trying test MTOM through JAX-WS, we found that the AssessmentDataStore
> can only be written once. It will fail for the second time. After
> investigation, it seems that the binary stream is not cached by the
> AssessmentDataStore, so each time a DelegatingStream will be created to
> handle the writeTo request. While the DelegatingStream is closed, it can not
> handle the writeTo request again.
> The suggestion is to cache the newly created attachement after it is created
> in AttachmentDeserializer
> The interface is:
> /**
