Magento\Email\Model\Template\Filter can't be intercepted

[kassner]

Hi,

Magento version: 2.0.6

I created a simple plugin: (class exists, but its contents does not interfere here).

<type name="\Magento\Email\Model\Template\Filter">
    <plugin name="escapenl2br" type="Vendor\Module\Plugin\EscapeNl2br" sortOrder="1"/>
</type>

But this results in a weird error message:

Warning: Declaration of Magento\Email\Model\Template\Filter\Interceptor::setTemplateProcessor($callback) should be compatible with Magento\Framework\Filter\Template::setTemplateProcessor(callable $callback) in /private/var/www/magento/var/generation/Magento/Email/Model/Template/Filter/Interceptor.php on line 7

Obviously, the code generated is wrong:

    public function setTemplateProcessor($callback)
    {
        $pluginInfo = $this->pluginList->getNext($this->subjectType, 'setTemplateProcessor');
        if (!$pluginInfo) {
            return parent::setTemplateProcessor($callback);
        } else {
            return $this->___callPlugins('setTemplateProcessor', func_get_args(), $pluginInfo);
        }
    }

Where I can dig into to fix this?

Thanks!

This seems already fixed in:
