Normalized paths not present in AppMaps with shallow-recorded spring framework classes

For the same app & appmap.jar, the HTTP server request events are different:

without spring framework events:

            "event": "call",
            "http_server_request": {
                "normalized_path_info": "/owners/:ownerId",
                "path_info": "/owners/2",
                "protocol": "HTTP/1.1",
                "request_method": "GET"
            },

with spring framework events:

            "event": "call",
            "http_server_request": {
                "path_info": "/owners/2",
                "protocol": "HTTP/1.1",
                "request_method": "GET"
            },

appmap.yml:

name: spring-petclinic
# Your project contains the directory src/main/java.
# AppMap has auto-detected the following Java packages in this directory:
packages:
- path: org.springframework.samples.petclinic
- path: org.springframework.web
  shallow: true
  exclude:
    - org.springframework.web.filter.OncePerRequestFilter

Start with the two attached AppMap JSON archives and the appmap.yml package configuration. Compare HTTP server request event generation with and without shallow-recorded Spring classes, focusing on why normalized_path_info is omitted. Done means normalized paths remain present in the affected AppMaps when Spring framework classes are shallow-recorded.
