Hi Oleg

This patch works fine for me on Hudson and for the user on the real environment. Will check
it in.

Many thanks

>             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

> 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.
