------------------------------------------------------------------

[~teofili] I fixed something in r1762273 \[0\]  but I don't know if it helps. I 
have a hard time to reproduce this. [~anchela] how can I create a user that has 
a {{rep:cache}} node?

> In OAK-3003 a persisted [principal 
> cache|http://jackrabbit.apache.org/oak/docs/security/principal/cache.html] 
> was introduced that creates _rep:cache_ nodes under authorizables.
> Creating a package for such authorizables will result in including the cache 
> node in there, which sounds wrong as that node is an implementation detail 
> which doesn't make sense to install anywhere; however that can be avoided by 
> proper filters.
> What is problematic is the installation phase, if an authorizable gets 
> packaged with FileVault (no rep:cache in the package) and the target 
> user/group has a rep:cache node itself the importer will try (and fail as 
> it's protected) to delete the persisted cache node if ImportMode is set to 
> UPDATE.
> In my opinion this is wrong, it should be possible to not touch such nodes on 
> package installation, regardless of the chosen ImportMode.
> {noformat}
> org.apache.jackrabbit.vault.packaging.impl.ZipVaultPackage Error during 
> install.
> javax.jcr.nodetype.ConstraintViolationException: OakConstraint0034: Attempt 
> to create or change the system maintained cache.
