Description

When using the EntityProvider.writeBatchRequest(batchParts, boundar); method to create a $batch request which contains BatchChangeSetParts the calculated Content-Length of the changeset body part is not correct (regarding to "http://www.w3.org/Protocols/rfc1341/7_2_Multipart.html").

This results in exception when using strict multipart parsers (like sample service at "http://services.odata.org/V2/OData/OData.svc/$batch") which response with:

--batchresponse_bbd3caec-0224-49c9-8bf0-75a1365853fb
Content-Type: multipart/mixed; boundary=changesetresponse_054f8f41-e12f-46bb-922b-3dc234e2f27b
