Oleg Kalnichevski commented on HTTPCLIENT-1362:
-----------------------------------------------
Sergey
This confusion is not of HttpClient making. The Socket#connect method is
supposed to throw SocketTimeoutException in case of a connect timeout [1]
whereas ConnectException is meant to signal an error connecting to a particular
remote endpoint (hence the message).
What we can do though is to re-use the message of the original exception when
re-throwing it as HttpHostConnectException.

> Confusing message in HttpHostConnectException

> TCP connection can fail with two different kind of errors: 'Connection timed'
> out and 'Connection refused'. When a connection error occurs HttpClient
> catches SocketException and replaces it with HttpHostConnectException. In
> addition to exception class it replaces exception message, changing original
> text with 'Connection to ... refused'. This message is confusing because it
> looks very much like SocketException 'Connection refused', but in fact it
> hides original 'Connection timed out'.
> Consider using different messages in HttpHostConnectException depending on
> parent exception.
