Joel Feenstra commented on JCR-2573:
------------------------------------
I am seeing a sporadic failure to read a file using webdav with Jackrabbit
2.1.0. If I share a nt:folder and apply permissions to it to make it read-only
for some users, sometimes I am unable to read the properties of an nt:file in
that folder. I tried our code against Jackrabbit 2.2-SNAPSHOT and it worked
fine. I tried to find out what change fixes the bug, and it appears to be
r950440. Are there plans to merge this into the 2.1 branch (I just saw it was
merged to 2.0).

> 1. Performance in access control evaluation
> =====================================================================
> - main focus on
> > read performance
> > resource-based access control in .a.j.c/s/authorization/acl/*
> - comparison admin vs. anonymous with full permissions
> - comparision between shortcut and ACL-evaluation.
> - comparison JR 1.4 vs JR 2.0 [actually i will compare Day's CRX as it
> already provided
> some custom AC stuff with JR 1.4]
> 2. Potential Problems
