Temporary root mapping "/" issue after startup [DATAREST-98]

Michael Wilmes opened DATAREST-98 and commented

After startup of application Spring Data Rest root ("/") controller mapping is failing:

1. curl "http://admin:admin@localhost:8080/api/"
{
  "cause" : null,
  "message" : "No mapping found on controller class org.springframework.data.rest.webmvc.RepositoryController!"
}

If I now access an SDR entity controller...

curl "http://admin:admin@localhost:8080/api/businessRule"
{
  "links" : [ {
    "rel" : "businessRule.search",
    "href" : "http://localhost:8080/api/businessRule/search"
  } ],
  "content" : [ ],
  "page" : {
    "size" : 0,
    "totalElements" : 0,
    "totalPages" : 0,
    "number" : 1
  }
}

...the "/" controller mapping that failed on first access works again magically:

url "http://admin:admin@localhost:8080/api/"
{
  "links" : [ {
    "rel" : "bcs",
    "href" : "http://localhost:8080/api/businessRule"
  }, {
    "rel" : "build",
    "href" : "http://localhost:8080/api/customer"
  } ],
  "content" : [ ]
}

Affects: 1.1.0.M1

Start by reproducing the startup sequence against the root endpoint at /api/, then access /api/businessRule and retry the root endpoint. Read the RepositoryController mapping behavior around startup and entity-controller access; done means the root mapping works on the first request as well as after an entity request.
