使用sonata管理包时已弃用的警告

我使用symfony2.7与sonata admin doctrine form bundle，我遵循官方安装说明，工作很好，除了一件事。在每次请求中，我都得到以下已废弃的警告，我不知道如何消除它。

Date:   2016-10-18 08:58:28
Fatal: array(
    ['type'] => 16384, 
    ['message'] => 'This class is deprecated since 3.2 and will be removed with the 4.0 release.Use Sonata'BlockBundle'Block'Block'Service'AbstractBlockService instead.', 
    ['file'] => '/www/managedoc/branch/hoffereka/app/cache/superadmin_dev/classes.php', 
    ['line'] => 8575, 
)

编辑:我附加了一个堆栈跟踪
