      Description

      I am trying to upload a file in chunks to the openstack-swift. Here is the snippet of the code I am using to upload a file named dom4j-1.6.1.jar in chunks.

      blobStore.putBlob("jclouds-example", blob) does work, but if I add multipart to the method, then I get NullPointerException: Null partETag.

                    ByteSource payload = Files.asByteSource(tempFile);
      	      Blob blob = blobStore.blobBuilder(objectName)
      	          .payload(payload)
      	          .contentDisposition("attachment; filename=dom4j-1.6.1.jar")
      	          .contentMD5(payload.hash(Hashing.md5()))
      	          .contentLength(payload.size())
      	          .contentType(MediaType.OCTET_STREAM.toString())
      	          .build();
                    System.out.println(blob.getMetadata().getName());
      	      // Upload the Blob 
      	      String eTag = blobStore.putBlob("jclouds-example", blob, multipart());
      

      Exception Stacktrace:
