Anthony Carlucci resolved RAVE-722.
-----------------------------------
Resolution: Fixed
Fix Version/s: 0.14
Assignee: Anthony Carlucci
Shindig's GuiceServletContextListener overrides the
ServletContextListener.contextDestroyed method to perform cleanup tasks when
the web application context is destroyed. However in Rave, we have a custom
GuiceBindingSpringContextLoaderListener class that we use instead of the
aforementioned class, and we apparently never implemented the contextDestroyed
function to invoke the Guice cleanup functions. Something in Shindig
2.5.0-beta2 finally brought this issue to light as the contextDestroyed
function has been missing all along.

> Key: RAVE-722
> URL: https://issues.apache.org/jira/browse/RAVE-722
> Project: Rave
> Issue Type: Bug
> Affects Versions: 0.14
> Reporter: Anthony Carlucci
> Assignee: Anthony Carlucci
> Fix For: 0.14
>
>
> Since the upgrade to Shindig 2.5.0-beta2, Rave's ROOT.war web archive can't
> be re-deployed to Tomcat without restarting the entire Tomcat process. It
> seems like it has to do with Shindig registering an EhCache class as an
> MBean, which apparently stays in the JVM between web context restarts, and
> Shindig doesn't seem to be removing it or handling that case properly.
> This will affect any deployments of Rave in environments, for example, where
> you plan to use Tomcat's auto-deploy feature to only redeploy a web
> application without restarting the entire container (such as a CI
> environment).
> HOW TO REPRODUCE
> ----------------------------------
> 1) Build and deploy Rave using the standard mvn install / mvn cargo:run
> commands
> 2) Force Tomcat to reload the web application by making a change the the
> ROOT.war file located in $RAVE_HOME/rave-portal/target/tomcat6x/webapps. Any
> easy way to do this is simply add a text file into the war.
> 3) Watch the Tomcat logs as the ROOT webapp reloads - you will eventually see
