Ian Boston commented on SLING-1531:
-----------------------------------
Unfortunately the upgrade to JR2.1 this did break Sakai Nakamura, not because
of Sling but because of the changes internally to Jackrabbit.
In Jackrabbit 2.1 ACLTemplate.Entry is now very private so its not possible to
control the construction of an ACL list prior to compilation which makes it
impossible to extend the Access control system that comes with Jackrabbit to
cover use cases that are not covered (like ACE's that are active based on time
or rules). At the moment I only have 2 solutions, fork Jackrabbit or take Sling
snapshots before this change into production, neither are particularly
attractive.
No need to reopen this, just recording an upstream impact.
