[jboss-dev-forums] [Design of POJO Server] - Not keeping track of deployment class loader

[scott.stark@jboss.org]

I finally looked into a shutdown error I have been seeing with the repository based profile service. There is a CNFE thrown from the deployers/profileservice-beans.xml ProxyFactory due to the incorrect TCL:

On startup we have a hack in the ProfileServiceBootstrap to take the first bootstrap DeploymentContext as the base TCL. I suppose the ShutdownHook should be going through the profile service to shutdown the deployments in phases and employ the same hack, but shouldn't there be an association in the ControllerContext to the install action class loader if it came from the TCL rather than the BeanMetaData?
