> While resolving a FileObject on an sftp target for a directory that does not exist on the target, SftpFileSystem.getChannel() is called and while trying to cd to the workingDirectory, an SftpException is thrown but the channel object is not released.
> This leads to many sftp channels kept opoen on the target system and consumes unnecessary resources.
> A simple patch of releasing the channel in the caught SftpException in SftpFileSystem line 125 would solve this issue.
