Michael Stämpfli commented on JCR-2450:
---------------------------------------
I created a small package, with which I was able to reproduce the problem. My
environment: Jackrabbit 2.0, Tomcat 6.0.20, MySQL 5.0, Ubuntu 9.04 64 bit.
To reproduce the problem you need to do the following steps:
* Download the WAR file attached to this issue.
* Deploy it to tomcat (or another servlet container)
* Go to http://localhost:8080/jackrabbit-test/repository/default/ with your
browser. Login with the standard admin credentials. This will trigger the
security manager, that will create the administrator user. Afterwards you will
see the file list of the default workspace.
* Stop tomcat.
* Restart tomcat.
* Go again to http://localhost:8080/jackrabbit-test/repository/default/. You
will then see the following error message:
{code:xml}

When I start Tomcat the first time, I see a log entry concerning the node
mentioned above.
11.03.2010 09:54:43 *DEBUG* ItemManager: invalidated item
cafebabe-cafe-babe-cafe-babecafebabe (ItemManager.java, line 991)
11.03.2010 09:54:43 *DEBUG* ItemManager: removing item
cafebabe-cafe-babe-cafe-babecafebabe from cache (ItemManager.java, line 935)
I don't know if this is severe since it will only be removed from the cache.
There are no other entries concerning this node.
The second time I start Tomcat, I see the following log entries:

Another thing: It could be that the source of the problem is in the class
BundleDbPersistenceManager. I also tried PostgreSQL instead of MySQL and got
the same error. Then I configured the webapp to use the file system instead of
a DB. It worked perfectly. I assume that BundleDbPersistenceManager does not
save node modifications properly.
> UserManager inconsistency
> -------------------------
>
> Key: JCR-2450
> URL: https://issues.apache.org/jira/browse/JCR-2450
> Project: Jackrabbit Content Repository
> Issue Type: Bug
> Components: jackrabbit-core, security
> Affects Versions: 1.6.0, 2.0-beta4
> Environment: Ubuntu 9.04 64bit, Tomcat 6.0.20, Jackrabbit 1.6 and
> 2.0-beta4
> Reporter: Michael Stämpfli
> Priority: Blocker
>
> I used the default class UserManagerImpl to add a user to my jackrabbit (1.6)
> environment. My application can successfully login to the repository with
> this user. As soon as I restart Tomcat, the login fails.
> I did some research and found out why. Obviously the user manager cannot find
> the user, I registered previously, anymore. Using WebDAV I made a connection
> to the security workspace. When I create a new user, a new node for this user
> is created in /jcr:root/rep:security/rep:authorizables/rep:users/admin. As
> soon as I restart Tomcat and login to the security workspace again (using
> WebDAV), I see that the user node moved to the root node. As a consequence
> the user cannot login to the repository because the user manager cannot find
> the user node anymore.
> In jackrabbit 2.0-beta4 I get a similar bug and I assume, that the root cause
> is the same as above. I log into the repository using the administrator
> account, which is created automatically with the class UserManagerImpl. When
> I restart Tomcat and try to login to the repository I get the error:
> javax.jcr.ItemNotFoundException: failed to build path of
> 55411ff4-d6c7-410a-a16e-5531e1c7afae: cafebabe-cafe-babe-cafe-babecafebabe
> has no child entry for 55411ff4-d6c7-410a-a16e-5531e1c7afae
