Yan Min Sheng updated CXF-4772:
-------------------------------
Attachment: AttachmentDeserializer.java
The suggestion fix is to cache the newly created attachement after it is
created in AttachmentDeserializer
> AssessmentDataStore do not cache the last attachment binary stream, so the
> DataHandler.writeTo() will fail if it is called for the second time
> ----------------------------------------------------------------------------------------------------------------------------------------------

> 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
> Labels: patch
> Attachments: AttachmentDeserializer.java
>
>
> 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:
