Josip Gracin commented on HTTPCLIENT-1478:
------------------------------------------
I think I'm also having this problem, and using 4.3.4 does not help, it hangs
forever. I'm using something like this to instantiate Spring's RestTemplate:
<bean id="restTemplate" class="org.springframework.web.client.RestTemplate">
<constructor-arg>
<bean
class="org.springframework.http.client.HttpComponentsClientHttpRequestFactory">
<property name="connectTimeout" value="10000" />
<property name="readTimeout" value="10000" />
</bean>
</constructor-arg>
</bean>
I start 'nc -l localhost:12000' to mock a non-responding server, and here's the
log:

> Key: HTTPCLIENT-1478
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1478
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpConn
> Affects Versions: 4.3 Final, 4.3.1, 4.3.2, 4.3.3
> Environment: All
> Reporter: Jonah Schwartz
> Priority: Minor
> Fix For: 4.3.4
>
>
> https calls ignore http.socket.timeout during SSL Handshake. This can result
> in a https call hanging forever waiting for socket read.
> In both SSLSocketFactory and SSLConnectionSocketFactory,
> sslsock.startHandshake(); is called before socket timeout is set on the
> socket. This means timeout is not respected during the SSL handshake, and the
> thread can hang with a stacktrace that looks like this:
> org.apache.http.impl.client.AbstractHttpClient.doExecute
> org.apache.http.impl.client.DefaultRequestDirector.execute
> org.apache.http.impl.client.DefaultRequestDirector.tryConnect
> org.apache.http.impl.conn.ManagedClientConnectionImpl.open
> org.apache.http.impl.conn.DefaultClientConnectionOperator.openConnection
> org.apache.http.conn.ssl.SSLSocketFactory.connectSocket
> org.apache.http.conn.ssl.SSLSocketFactory.connectSocket
> sun.security.ssl.SSLSocketImpl.startHandshake
> sun.security.ssl.SSLSocketImpl.startHandshake
> sun.security.ssl.SSLSocketImpl.performInitialHandshake
> sun.security.ssl.SSLSocketImpl.readRecord
> sun.security.ssl.InputRecord.read
> sun.security.ssl.InputRecord.readV3Record
> sun.security.ssl.InputRecord.readFully
> java.net.SocketInputStream.read
> java.net.SocketInputStream.socketRead0
