Relative symbolic links with .. is not resolved properly by sftp readLink

Using sftp to resolve symbolic links doesn't return proper resolution in case symbolic link contains ..
Since version 1.1 the sendLink function of SftpSubsystem uses
normalizedPath = SelectorUtils.normalizePath(unixPath, "/");
to normalize path
This function however return invalid path in case link contains ".."
So for example if link is "../test/file" than normalizePath returns "test/file" which is invalid because in can not be resolved properly in the context of the current directory which symbolic link is referring to.
