Description

We noticed the behavior change in the batch processing between V2 2.0.0 and a later version from 2.0.1 including the current 2.0.5-SNAPSHOT.

The batch request that is accepted by the 2.0.0 service is no longer accepted when a later version of library is used.

Concretely, when using olingo's odata2 my-car-service service, using the batch request message (attached in this ticket), the service returns the the following error when using a later version of the library.

HTTP/1.1 400 Bad Request
Content-Type: application/xml
DataServiceVersion: 1.0
Date: Thu, 23 Jul 2015 14:14:16 GMT
Content-Length: 203
Server: Jetty(8.1.14.v20131031)

It seems to be something has been changed in the way the batch's content is processed. It is not clear if this was an intended behavior change or unintended.

Please see the attached odata2-batch-reqs.tar.gz file which contains the request files and a short description.
