我最近升级到了mysql：mysql-connector-java：5.1.34连接器。我的Grails版本是2.2.4。 MySQL版本是5.6.10。升级进行得非常顺利，应用程序本身似乎也很顺利。但是，我的一个测试应用程序失败了 发生以下错误：
Error Error executing script TestApp:

我对网络用户进行了双重检查，据我所知，该帐户已正确定义并具有与root相当的admin权限。在我的个人数据库开发盒和jenkins构建系统上都发生了这种情况。
我在日志中看不到任何内容，使用--stacktrace运行并没有给我任何有用的信息，谷歌搜索并没有将此显示为常见错误。
