      outerInstance - the outer instance to supply as the first argument to the constructor; empty, for top-level classes
      extensionContext - the current ExtensionContext
      extensionRegistry - the ExtensionRegistry to retrieve ParameterResolvers from
      interceptorCall - the call for intercepting this constructor invocation via all registered interceptors
