--------------------------------------------
Summary: org.apache.http.conn.ssl.SSLSocketFactory no longer
throws ConnectTimeoutException
Key: HTTPCLIENT-1940
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1940
Project: HttpComponents HttpClient
Issue Type: Bug
Components: HttpClient (classic)
Affects Versions: 4.5.3
Reporter: Marcelo Cenerino
Attachments: ConnectExceptionTest.java
We are upgrading httpclient from 4.2.3 to 4.5.3. We wanted to do the upgrade in
steps: first we just bump the versions and then we gradually refactor the
existing code to use the new builder-based api.
It turns out that there is a behavior change in
"org.apache.http.conn.ssl.SSLSocketFactory" (which is deprecated in 4.3+): in
case of a connect timeout, it does not translate the exception to
ConnectTimeoutException. This is inconsistent with the also deprecated
"org.apache.http.conn.scheme.PlainSocketFactory". In the 4.2.x series, the
exception was converted. These are likely the commits that caused this change:
* Exception translation moved to an abstract class:
[https://github.com/apache/httpcomponents-client/commit/e34e868ddc96b873a09b20e4911bc64fe8caf069#diff-2b61663f90e19b0024cea23ce9e5e791]
* Abstract class removed without moving the exception translation code back to
SSLSocketFactory:
[https://github.com/apache/httpcomponents-client/commit/d04b7baa642e7192bddb8e0ad26c7504c6908c85#diff-2b61663f90e19b0024cea23ce9e5e791]
I attached a test that reproduces the bug: [^ConnectExceptionTest.java]
This bug is not reproducible with the new builder api. However, given that the
old api was kept to maintain backwards compatibility, it is reasonable to
expect the old behavior.
As workarounds to this issue, one can either update the code and use the new
api or catch the java.net.SocketTimeoutException and check that the message is
"connect timed out".
Given that the bug hides in deprecated code and there are workarounds, maybe it
is not worth fixing it. In that case, please feel free to close this issue.
Otherwise, I can submit a patch.
