Different (wrong) assets names when use function jpegoptim in web request and assetic:dump command

[PeterZhukov]

My config:

assetic:
    debug:          '%kernel.debug%'
    #use_controller: '%kernel.debug%'
    use_controller: false
    filters:
        cssrewrite:
            apply_to: '\.css$'
        jpegoptim:
            bin: "%kernel.root_dir%/../bin/jpegoptim.exe"
            max: 100
    twig:
        functions:
            jpegoptim: ~

Template:
{{ jpegoptim('@AppBundle/Resources/public/images/example2.jpg') }}

When I refresh page in broser I get following string:
/symfony/web/assetic/d05ce4a.jpg
But when I execute command assetic:dump, I get following assets intalled:
11:17:23 [file+] D:\www\testphp.local\symfony\app/../web/assetic/b3aed8d.jpg

Why this happens:

When page is refreshed, next functions calls happens:

AsseticFilterInvoker : invoke,
AssetFactory : createAsset,
AssetFactory : generateAssetName

in AssetFactory : createAsset this happens:

        if (!isset($options['output'])) {
            $options['output'] = $this->output;
        }
...
        if (!isset($options['debug'])) {
            $options['debug'] = $this->debug;
        }
...
        if (!isset($options['root'])) {
            $options['root'] = array($this->root);
        } else {
            if (!is_array($options['root'])) {
                $options['root'] = array($options['root']);
            }

            $options['root'][] = $this->root;
        }

so basically, $options['debug'], $options['root'] keys are always set to something, then in AssetFactory : generateAssetName function filters $options keys not in 'output', 'debug', 'root', and then creates name based on $inputs, $filters (this 2 doesn't matter for this issue) and $options:
return substr(sha1(serialize($inputs).serialize($filters).serialize($options)), 0, 7);

But when i ussue command: assetic:dump, then next functions calls happens:

AsseticNodeVisitor : checkNode,
AssetFactory : generateAssetName

in AsseticNodeVisitor : checkNode there is not setting for $options['output'], $options['debug'], $options['root'] like in AssetFactory : createAsset, so in AssetFactory : generateAssetName $options becomes empty array (AsseticNodeVisitor : checkNode even doesn't send $options to AssetFactory : generateAssetName).
Then next functions calls happens:

TwigFormulaLoader : loadNode (here - } elseif ($node instanceof AsseticFilterNode) { - branch will be execute),
AssetFactory : generateAssetName

again, there is no settings for $options['debug'], $options['root'] and so on (but in this case $options is passed to AssetFactory : generateAssetName, but it is different array then in web request because of ['debug'] and ['root'] settings in AssetFactory : createAsset in web request).

Because of this - result assets names are different, and it is impossible to use jpegoptim in production mode (use_controller: false).

May be I'm doing something wrong?
