It seems like $templatePath defined by $this->kernel->locateResource('@TimegrydOpcacheResetBundle/Resources/template/opcacheReset.php') on line 76 can also be of type array; however, Symfony\Component\Filesystem\Filesystem::copy() does only seem to accept string, maybe add an additional type check?
