Subject [jira] [Commented] (HTTPCLIENT-1485) Wrong type of exception raised because of hardcoded string-compare
Date Sat, 22 Mar 2014 14:08:38 GMT

    [ https://issues.apache.org/jira/browse/HTTPCLIENT-1485?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13944081#comment-13944081
] 

Sebb commented on HTTPCLIENT-1485:
----------------------------------

I'm not sure what defines the OS timeout.

But the point is that most other errors that generate a ConnectException will happen immediately
or at least within a few seconds.

So if the connect takes significantly longer, it is most likely going to be a connect timeout
rather than some other error.
As it stands, some timeouts are currently reported incorrectly because the text matching is
not generic.
(AFAICT does not work on FreeBSD or WindowsXP)

The worst that could happen with opton 3 is that some other error is reported as a timeout.
But given that the connect has taken a long time to reach the exception, timeout seems a reasonable
response.
In any case, the orginal exception is passed to the timeout exception.
