Deployers and the deploying classes are in separate class loader hierarchies 
-----------------------------------------------------------------------------

         Key: GERONIMO-1931
         URL: http://issues.apache.org/jira/browse/GERONIMO-1931
     Project: Geronimo
        Type: Bug
    Security: public (Regular issues) 
  Components: deployment  
    Versions: 1.1    
    Reporter: Dain Sundstrom
     Fix For: 1.2


The deployers are loaded from the main KernelConfiguraitonManager, where as when we deploy
the new deployments are loaded from a private SimpleConfigurationManager.  This means two
classloaders are completely separate and deployers see different versions of the spec classes.
 Therefor, the deployers can't make use of instanceof and can use code like this:

TimedObject.class.inAssignable(beanClass)

This makes deployers unnecessarily complex and error prone.  This can easily be addressed
by having the private SimpleConfigurationManager in the DeploymentContext first check main
KernelConfigurationManager to see if the configuration exists before reloading it from disk.
