A Connection close could cause an SSLIOSession to be incorrectly considered as 
closed in some environments

                 Key: HTTPCORE-193
                 URL: https://issues.apache.org/jira/browse/HTTPCORE-193
             Project: HttpComponents HttpCore
          Issue Type: Bug
          Components: HttpCore NIO
    Affects Versions: 4.0
         Environment: This has been seen by an Apache Synapse user, as well as 
by me on the Hudon build machine
SunOS hudson.zones.apache.org 5.10 Generic_137112-02 i86pc i386 i86pc
This is not seen on my Linux box, Linux asankha 2.6.24-19-generic #1 SMP Wed 
Aug 20 17:53:40 UTC 2008
x86_64 GNU/Linux
            Reporter: Asankha C. Perera
            Assignee: Asankha C. Perera
             Fix For: 4.1
         Attachments: HTTPCORE-193.patch

This could be seen on the SunOS machine Hudson, and also if a breakpoint is 
placed at the line receiveEncryptedData() in SSLIOSession:isAppInputReady() to 
delay its execution slightly

It seems like the following lines are the cause of the problem:

        int bytesRead = receiveEncryptedData();
        if (bytesRead == -1) {
            this.status = CLOSED;
        }

The Channel not having any more bytes does not indicate a close, since there 
still could be unencrypted data. Just removing the lines that mark the session 
as closed seems to fix the issue - but should be reviewed.
