Subject [jira] Created: (GERONIMO-948) Need reference counting on load/start of configurations

Need reference counting on load/start of configurations
-------------------------------------------------------

         Key: GERONIMO-948
         URL: http://issues.apache.org/jira/browse/GERONIMO-948
     Project: Geronimo
        Type: Bug
  Components: kernel  
    Versions: 1.0-M5    
 Reporter: David Jencks
 Assigned to: David Jencks 
     Fix For: 1.0-M5


When you load/start a configuration, it loads and starts its ancestors and keeps track of
what it loaded and what it started, and undoes this when you stop/unload it.  This will create
big problems if you
load A
load B (with a common parent)
unload A (unloading common parent of B)
unload B

Solution appears to be to count how many descendants use a config and only stop/unload if
count reaches 0.  Code to do this should probably be in the ConfigurationManager.
