angela commented on OAK-8234:
-----------------------------

[~stillalex], the patch for {{AuthorizationConfigurationImpl}} looks good to 
me. i still think it's wrong to ignore the test case that fails. in fact the 
test class that contains the failing test is called 
{{PermissionProviderImplTest}} but apparently it doesn't test 
{{PermissionProviderImpl}} but the {{AllPermissionProviderImpl}}. So quite 
obviously it doesn't test the class it claims to test.... adjusting the 
{{createPermissionProviderImpl}} method should do the trick... maybe creating 
{{PermissionProviderImpl}} instance manually instead of letting the 
configuration create it?
Also: I would like the new class {{AllPermissionProviderImpl}} to come with a 
dedicated test class with unit tests. Also an extra test for 
{{AuthorizationConfigurationImpl}}...

> There was already a lot of work done here to improve efficiency of admin 
> sessions, but we can still do better by simply not creating many of the 
> objects needed as parameters for the {{CompiledPermissions}} which will be 
> ignored anyway in the case of admin sessions.
> Ex: There are a lot of immutable trees (created via 
> {{PermissionUtil.getReadOnlyTree(tree, immutableRoot)}}) that are not used 
> for the evaluation.
> Thanks to [~mreutegg] for spotting this one!
