    Resolution: Fixed

[~Csaba Varga] Thanks for the patches, I've applied them

In addition I increased the version of the spi package as a new constant has 
been added

>                 URL: https://issues.apache.org/jira/browse/SLING-3524
>             Project: Sling
>          Issue Type: Improvement
>          Components: API, JCR, ResourceResolver
>    Affects Versions: Resource Resolver 1.0.6
>            Reporter: Alexander Klimetschek
>            Assignee: Carsten Ziegeler
>            Priority: Major
>             Fix For: API 2.18.2, JCR Resource 3.0.10, Resource Resolver 1.6.2
>
>          Time Spent: 1h 40m
>  Remaining Estimate: 0h

> {{ResourceResolver.clone()}} will reuse the same JCR session in case it was 
> created by passing an existing session using 
> {{JcrResourceConstants.AUTHENTICATION_INFO_SESSION}}. If you need a clone of 
> the resource resolver to pass into a new, separate thread, and use 
> {{ResourceResolver.clone(null)}}, you will actually share the session, but 
> this is not obvious. The problem is that a JCR session cannot be shared 
> across threads.
> The javadocs of clone() say "the same credential data is used as was used to 
> create this instance".
> There are a few problems with this:
> - seeing the session object itself as "credential data" is unintuitive
> - in my code, I have no idea what the original credential data was, so I 
> don't know what kind of credential data it was to make the right decision
> - since sharing a JCR session is to be avoided at all times, the resource 
> resolver should prevent one from this
> A solution would be if a plain {{ResourceResolver.clone(null)}} would return 
> a session that impersonated itself, abstracting this from the resource 
> resolver user. Additionally, it might be worth looking that clone always 
> returns a new session, unless specifically stated.
