-------------------------------------
Added information.
> Client fails window adjust above INT_MAX
> ----------------------------------------
>
> Key: SSHD-1244
> URL: https://issues.apache.org/jira/browse/SSHD-1244
> Project: MINA SSHD
> Issue Type: Bug
> Affects Versions: 2.8.0
> Reporter: Ryosuke Kanda
> Priority: Minor
>
> If the new window size specified by SSH_MSG_CHANNEL_WINDOW_ADJUST exceeds
> INT_MAX, it will not be recognized correctly.
> I think the cause is in the following places:
> org.apache.sshd.common.channel.Window.expand（int）
>
> I am doing machine translation, so please allow it to be unnatural.
>
> I encountered this issue when I was using ProFTPD as an SFTP server.
> The version of ProFTPD is 1.3.5e.
> The SFTP feature of ProFTPD notifies 2 ^ 32-1 bytes as the initial window
> size by default.
> I've confirmed that SSHD can handle this without any problems, so I sent a
> 4GB file to see what happens when Window Adjust is done.
> As a result, a Window Adjust was done and SSHD was unable to handle this
> successfully.
