Subject [jira] [Created] (HTTPCLIENT-1485) Wrong type of exception raised because of hardcoded string-compare
Date Mon, 17 Mar 2014 10:26:42 GMT
Dominik Bennersdorfer created HTTPCLIENT-1485:

             Summary: Wrong type of exception raised because of hardcoded string-compare
                 Key: HTTPCLIENT-1485
                 URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1485
             Project: HttpComponents HttpClient
          Issue Type: Bug
          Components: HttpClient
    Affects Versions: 4.3.3, 4.3.2
            Reporter: Dominik Bennersdorfer

In the lines org.apache.http.impl.conn.HttpClientConnectionOperator.java:134-143 we found
that the message of the ConnectException is compared to the hardcoded string "Connection timed
This can causes wrong break down to the http-client own Exception-types on Systems with other

} catch (final ConnectException ex) {
	if (last) {
		final String msg = ex.getMessage();
		if ("Connection timed out".equals(msg)) {
			throw new ConnectTimeoutException(ex, host, addresses);
		} else {
			throw new HttpHostConnectException(ex, host, addresses);

To illustrate the Problem see the following Example:
On our server the locale is set to "de_AT.ISO-8859-15@euro" 
with a simple wget i get this (see the message in last line)

root@MRW-MJA-vml1:/tmp# wget http://www.google.at:81
--2014-03-14 12:46:44--  http://www.google.at:81/
Auflösen des Hostnamen www.google.at...
Verbindungsaufbau zu www.google.at||:81... fehlgeschlagen: Die Wartezeit für
die Verbindung ist abgelaufen.

after changing the locale to "en_US.ISO-8859-15" i get the following:

root@MRW-MJA-vml1:/tmp# wget http://www.google.at:81
--2014-03-14 12:43:33--  http://www.google.at:81/
Resolving www.google.at...
Connecting to www.google.at||:81... failed: Connection timed out.

Example with httpclient 4.3.3 (parts from our tracing):
Exception<org.apache.http.conn.HttpHostConnectException> Message<Connect to ****
failed: Die Wartezeit für die Verbindung ist abgelaufen> 
Cause<java.net.ConnectException: Die Wartezeit für die Verbindung ist abgelaufen>

We excpected to get a ConnectTimeoutException rather than a HttpHostConnectException
