----------------------------------------
I can confirm the issue.
Server: Linux 2.6.18-348.1.1.el5 #1 SMP Tue Jan 22 16:19:19 EST 2013 x86_64
x86_64 x86_64 GNU/Linux
AS: JBoss 7.1.1
Java version: 1.7.0_17
httpcore-nio version: 4.2.4
Timeout set: 5000ms, but the exception is thrown after one millisecond.
Every now and then such an exception is thrown (I improved the output with
request data):

The request doesn't reach the counterpart.
> SocketTimeoutException occurs too soon

> Key: HTTPASYNC-39
> URL: https://issues.apache.org/jira/browse/HTTPASYNC-39
> Project: HttpComponents HttpAsyncClient
> Issue Type: Bug
> Affects Versions: 4.0-beta3
> Reporter: Clinton Nielsen
>
> In a highly concurrent environment, where SocketTimeout is set to 30,000
> milliseconds, we are often seeing a timeoutexception after only 0 or 1 or 2
> milliseconds has actually passed.
> I get the impression that in the AbstractIOReactor timeoutCheck function,
> session.getLastAccessTime is being called on the session before the
> lastAccessTime is set on the session for the current session (ie. the
> lastAccessTime being retrieved is the time that was set on the session object
> for the previous http session)
