Martin Renner closed CXF-2940.
------------------------------

    Resolution: Invalid

Andreas, you are right. The API doc of DataSource clearly mentions, that a new InputStream has to be created for every call to {{getInputStream}}.

I am closing this issue as _Invalid_.

> Under some circumstances, AttachmentOutInterceptor does not close the input stream that it uses to read the contents of an attachment and to stream it to the client. This can lead to a resource leak, because those input streams often belong to server resources like database results, files from the server's filesystem etc.
> The stream gets closed, if an exception occurs _while_ streaming the content of one particular input stream to the client. However, the streams are not closed, if
> * an exception occurs on the outbound chain somewhere between the very first interceptor and AttachmentOutInterceptor.
> * there are several attachments, writing of one fails (maybe because the client closed the connection) and there are some more attachments left. Then the streams of those outstanding attachments won't get closed.
