> in cases where the Servlet Container reuses parsed InputStreams - what seams
> to be the case with Tomcat 7.
> The reason for that is that the finalize() method of the StreamSource does
> call close() on the initially parsed InputStream. This might results in
> Situations where close() is called on an InputStream that is currently used
> by an other connection.
> To Solve this the following two adaptions are planed:
> 1. The StreamSource MUST NOT close parsed Streams.
> 2. Add the Requirement that the ContentItemFactory needs to consume all data
> from parsed ContentSource implementation before returning from create**
> methods.
> While (1) solves the reported issue and also allows for reusing streams by
> the container (2) is required to allow users outside a container to know when
> they can safely close streams.
