+ <strong>JSSE prior to Java 1.4 incorrectly reports socket timeout.</strong>
+ </p>
+ <p>
+ Prior to Java 1.4, in Sun's JSSE implementation, a read operation that has
timed out incorrect
+ reports end of stream condition instead of throwing
java.io.InterruptedIOException as expected.
+ HttpClient responds to this exception by assuming that the connection was
dropped and throws a recoverable
+ HTTP exception: Error in parsing the status line from the response: unable
to find line starting with "HTTP".
+ It should instead report "java.io.InterruptedIOException: Read timed out".
If you see the "unable to find
+ line..." message when working with an older version of JDK and JSSE, it
can be caused by the timeout
+ waiting for data and not by a problem with the connection.
+ </p>
+ <p>
+ <strong>Work-around:</strong> One possible solution is to increase the
timeout value as the server is
+ taking too long to start sending the response. Alternatively you may
choose to upgrade to Java 1.4 or
+ above which does not exhibit this problem.
+ </p>
+ <p>
+ The problem has been discovered and reported by Daniel C. Amadei.

+ <strong>HttpClient does not work with IBM JSSE shipped with IBM Websphere
Application Platform</strong>
+ </p>
+ <p>
+ Several releases of the IBM JSSE exhibit a bug that cause HttpClient to
fail while detecting the size
+ of the socket send buffer (java.net.Socket.getSendBufferSize method throws
java.net.SocketException:
+ "Socket closed" exception).
+ </p>
+ <p>
+ <strong>Solution:</strong> Make sure that you have all the latest fix
packs applied. HttpClient users
+ have reported that IBM Websphere Application Server versions 4.0.6,
5.0.2.2, 5.1 do not exhibit the problem.
