Support for Containers with 'hierarchic BeanManagers' This is mostly useful for EAR applications. Some EE Container scan the common shared EAR lib path and reuse this information for the webapps in the EAR. This is actually the only approach a container can do to prevent mem leaks and side effects spreading to different webapps. Of course this also means that the webapps get their own (different) instances of an Extension. To acknowledge this solution we provide a mechanism to lookup 'parent Extensions' which is very similar to handling parent ClassLoaders. All your Extension has to do is to register itself in BeforeBeanDiscovery. Later at boot time the Extension can lookup it's parent Extension instance and e.g. check which classes got scanned in the parent ClassLoader. The ExtensionInfo automatically gets removed if the webapp gets undeployed.
