    I haven't got my head around the new API yet - this is just a preliminary 
comment.
    
    It is a bit of a change around authentication but I think it is the right 
thing to do.  It seems to me that the only other choice is not to migrate to 
the new API which over time will become a nuisance.
    
    Documenting the migration (for the release notes) will be helpful - maybe 
an example for user/password in the HttpOp class javadoc. If someone can grok 
that, they can see how to migrate their own code.
    
    One thought - it looks like the new style is to treat `CloseableHttpClient` 
as a one time use object. That means a try-resource in `HttpOp.exec`.  I'm not 
sure how widespread this is. `getDefaultHttpClient` `setDefaultHttpClient` 
should be changed to be a `HttpClientBuilder`?

>          Issue Type: Dependency upgrade
>          Components: ARQ
>    Affects Versions: Jena 2.11.0
>            Reporter: Rob Vesse

>            Priority: Minor

> As of 2.11.0 ARQ centralizes all HTTP operations through HttpOp which relies 
> on Apache HTTP Client.  Currently we are using 4.2.3 while the latest stable 
> release is actually 4.3.1
> Therefore we should look at upgrading our code to use the latest version 
> which may entail some refactoring since there appears to have been some 
> breaking changes across the minor version bump which users have seen in usage 
> - e.g.
