Reading description through wildcards doesn't work anymore

Wildcard queries for resource description seems to always return the root resource description:

[domain@localhost:9999 /] /host=local/server-config="*":read-resource-description
{
"outcome" => "success",
"result" => [{
"address" => [],
"outcome" => "success",
"result" => {
"description" => "The root node of the domain-level management model.",

[...]
}

it used to return the description of the resources at that address.
