Bo Xing created HTTPCORE-391:
--------------------------------
Summary: SocketTimeoutExceptions thrown in case of connection
timeouts
Key: HTTPCORE-391
URL: https://issues.apache.org/jira/browse/HTTPCORE-391
Project: HttpComponents HttpCore
Issue Type: Improvement
Components: HttpCore NIO
Affects Versions: 4.3.2
Reporter: Bo Xing
Fix For: 4.3.3
When a connection timeout happens, a SocketTimeoutException is thrown with no
context at all. As a result, applications are unable to differentiate between
connection timeouts and actual socket timeouts. Is there a reason why it is not
a ConnectionTimeoutException that is thrown here? I understand that
ConnectionTimeoutException is part of the sync client library. But can we
create a similar one in the async client library, and let the RouteSpecificPool
class throw it?
Please advise. Thanks!
The stack trace is as follows.
