public abstract <T> Collection<ExtensionComponent<T>> find(Class<T> type)

    This method is called only once per the given type after all the plugins are loaded, so implementations need not worry about caching.
    
    Type Parameters:
    
    T - The type of the extension points. This is not bound to ExtensionPoint because of Descriptor, which by itself doesn't implement ExtensionPoint for a historical reason.
    
    Returns:
    
    Can be empty but never null.
