Invoke the registered extension handler code in the extension context. The
extension context wraps the method that gets executed and a full customized configuration
(both instance and method specific configuration customizers have been applied). The
extension context is registered with the underlying handle to configure the handle when
executing the registered {@link ExtensionHandler}.

@param args The arguments to pass into the extension handler
@return The result of the extension handler invocation
