error msg in http:request

[caox]

After updated erlang version to R13B04, I found unexpected error 
messages prompted when using http:request to call an invalid URL. Is 
this reasonable?

  (ewp@REDACTED)1> Url="http://127.0.0.1:3002/mobilebank/srvStatus.jsp".
"http://127.0.0.1:3002/mobilebank/srvStatus.jsp"
(ewp@REDACTED)2> http:request(Url).
{error,{error,{connect_failed,{#Ref<0.0.0.271>,
                                {error,econnrefused}}}}}
(ewp@REDACTED)3>
