>             Project: Jackrabbit
>          Issue Type: Bug
>          Components: jackrabbit-webapp
>    Affects Versions: 1.4
>         Environment: Tomcat 5.5

> I just moved setup model for the Jackrabbit repository from a Tomcat-global JNDI-datasouce
to a autonomous server connected via RMI to get rid off the problem of a total restart of
the tomcat, if e.g. something is changed in the jackrabbit setup.
> But the restart of the RMI component of the jackrabbit server package will fail, because
on shutdown the rmi binding isn't released. From that, at restart, the socket is still in
use and the (just) RMI component fails to start. In the other hand, it isn't possible to connect
to the server through the remaining rmi component; you'll get a EOF-exception in RMI communication.
Of course, a complete restart of the Tomcat will help, but isn't appropriate. 
> It looks to me like just some release on shutdown is missing. May somebody provide a
patch?
