/**
*
* {@link ComponentAdapter} implementation that caches the component instance.
*
*
* This adapter supports components with a lifecycle, as it is a
* {@link Behavior lifecycle manager} which will apply the delegate's
* {@link org.picocontainer.LifecycleStrategy lifecycle strategy} to the cached
* component instance. The lifecycle state is maintained so that the component
* instance behaves in the expected way: it can't be started if already started,
* it can't be started or stopped if disposed, it can't be stopped if not
* started, it can't be disposed if already disposed.
