>
> When setting stream=true on XPathEntityProcessor a separate thread is created
> to read whatever Reader is being used for rows while the original thread
> pumps a BlockingQueue. This design allows the Reader to be read even when
> DIH cannot process documents as quickly as they become available in the
> Reader.
> This design has questionable value. It adds complexity to the code with
> unclear benefits to the user.
> At any rate, the code incorrectly uses the BlockingQueue API:
> 1. Arbitrarily sets a 10 second timeout and fails when this timeout elapses
> before a row becomes available.
> 2. Fails to check the return code when calling offer() to see if the item
> was successfully added or if the queue is full.
> 3. Fails to stop consuming the Reader even after an import has failed or
> been aborted.
> The effect is that if a URL being processed pauses more than 10 seconds to
> think in between streaming rows, the XPathEntityProcessor fails. Setting the
> readTimeout and connectionTimeout attributes on the dataSource does not
> address this bug because XPathEntityProcessor imposes its own timeout,
> hard-coded to 10 seconds.
