How to correctly handle the EOF when closing ssh connection

[qing tang]

Hi Guys,

I got one issue when close the ssh connection. Could you please help to check?

When I tried to close it, but sshj lib reported "Broken transport; encountered EOF".

How to correctly handle this exception?  Any other steps needed to clean the resource to avoid memory leak?
