> Key: JCR-396
> URL: http://issues.apache.org/jira/browse/JCR-396
> Project: Jackrabbit
> Type: Bug
> Components: rmi
> Versions: 1.0
> Environment: Jackrabbit Rev. 393410 WebApp
> Reporter: Felix Meschberger
> Assignee: Felix Meschberger
> Fix For: 1.0.1
> Attachments: RepositoryStartupServlet_patch_fm_20060412.diff
>
> The jcr-server/webapp project contains a servlet - RepositoryStartupServlet -
> which may be used in a web app to start a repository and optionally register
> the repository with JNDI and RMI. To register the repository with JNDI, the
> jcr-rmi library is used to create a Remote repository instance, which is
> registered with the RMI registry. Inside the RMI implementation mechanisms
> based on stub classes created by the RMI compiler are created to make the
> remote repository available remotely. This includes creating a object table
> to map remote references to local objects. This table stores references to
> the local object as weak references to support distributed garbage collection.
> Over time, it may now be that this remote repository instance is actually
> collected and the object table cannot access it anymore thus preventing the
> repository from being accessed remotely. To prevent this from happening, the
> RepositoryStartupServlet must keep a strong reference to the remote
> repository and drop this reference when the servlet is destroyed and the
> repository unregistered.
> *NOTE:* This is an issue to all long running applications which publish
> repository instances over RMI using the jcr-rmi library.
