REST get no parameters

[Hans Bakker]

Sorry Girish me again,

if i create a simple method service with action GET and no parameters , 
i get a 500 http error,

like:

curl -X  GET https://localhost:8443/rest/services/findProductById -H 
"Accept: application/json" -H "Authorization: Bearer $token" --insecure
{
  "statusCode" : 500,
  "statusDescription" : "Internal Server Error"
}

regards,

Hans
