Major Description
When sending a conditional request (If-None-Match for example) and the backend responds with a 304 Not Modified, the response contains an HttpEntity but you get a NullPointerException whenever to try to call one of the methods :
- org.apache.http.HttpEntity.getContent()
- org.apache.http.HttpEntity.writeTo(OutputStream)
I would expect getEntity() to return null if there is no entity in the response.
As a workaround I can test on the contentLength before calling these methods and call EntityUtils.consume(entity) to get sure that the connection is released but this makes things more complicated.
