RuntimeException: Recursive router rebuild detected.

Problem/Motivation

This is a tricky one and took me time to figure out... Installing a module defining JSON API resources during site install such as Commerce API can trigger a

RuntimeException: Recursive router rebuild detected.

exception.

This seems to be caused by the exceptions thrown from ResourceRoutes::ensureResourceImplementationValid() by the following check:

    elseif (empty($route->getDefault('_jsonapi_resource_types'))) {
      throw new RouteDefinitionException("The $route_name route definition's _jsonapi_resource_types route default must declare at least one resource type.");
    }

For some reason, during the installation, the following:

    $order_resource_types = $this->getResourceTypesForEntityType('commerce_order');

returns an empty array causing the exception to be thrown which seems to trigger a router rebuild.
