post request with Content-Length >1024 bytes failed

Description of the problem including expected versus actual behavior:
when trying to load template with command:
curl -v -XPUT http://localhost:9200/_template/template_esb -d @/path/to/template_esb.json

I got empty response from server in case template file >1024 bytes.
In ES I got:
[2016-08-11 14:19:10,657][WARN ][http.netty4 ] [7o-5HeP] caught exception while handling client http traffic, closing connection [id: 0x83358c12, L:/127.0.0.1:9200 - R:/127.0.0.1:39434] java.lang.UnsupportedOperationException: unsupported message type: DefaultFullHttpResponse (expected: ByteBuf, FileRegion)

If I cut file to be less than 1024 bytes then template created successfully.
The same template works fine in 5.0.0-alpha1

Steps to reproduce:

1. start ES
2. prepare template file with size >1024 bytes
3. curl -XPUT http://localhost:9200/_template/template_esb -d @/path/to/template_esb.json

Closing as a duplicate of #19834. You can workaround the issue by adding -H "Expect:" to your curl command
