Ian Boston resolved SLING-1528.
-------------------------------

    Resolution: Fixed

Fixed, 

as per discussion, the format is back to a json map, with a new property "order" added to each object to reflect its order in the ACL. The Integration tests have been adjusted to work with the old format.

> Hi,
> I am not certain if this was intentional but the format of GetAclServlet was
> changed by [1].
> Previously the format was a map keyed by principalid, now its an array
> containing objects.
> I can understand that an array maintains the order of the ACE's in the ACL which
> is required by parts of SLING-1458, however its not backwards compatible and
> breaks all existing clients that were expecting a map. Since that might be quite
> a lot of code, embedded in Client side Javascript apps and server side http
> clients, wouldn't it be better to provide keep the format and add a sequence
> number to the map objects? , eg
> Old format:
> {"user1-1274468817" : {"granted":["jcr:read"]}}
> New format
> [{"principal":"user1-1274468817","granted":["jcr:read"]}]
> Suggested new format
> {"user1-1274468817" : {"granted":["jcr:read"], "sequence": 0}}
> I know the suggested new format is not as natural, however it won't require all
> clients to recode.
> If we really do want to migrate to an array, then a new selector might be the
> way.
> eg ..../node.aclarray.json
> WDYT ?

> After leaving this for a few days, there appears to be no objection to changing the format back to the original with an additional sequence property.
