Apache Log4j 2.0-alpha1中的錯誤？

Question

我正在使用Windows 7（x32），Jre7，IntellijIDEA 12。

我的pom.xml片段：

    <dependency>
        <groupId>org.apache.logging.log4j</groupId>
        <artifactId>log4j-api</artifactId>
        <version>2.0-alpha1</version>
    </dependency>

    <dependency>
        <groupId>org.apache.logging.log4j</groupId>
        <artifactId>log4j-core</artifactId>
        <version>2.0-alpha1</version>
    </dependency>

我的普通Java類：

// Imports omitted

public class Controller
{
    private static Logger logger = LogManager.getLogger(Controller.class.getName());

    public static void main( String[] args )
    {
        logger.error("Entering application.");
    }
}

我有一個例外：

是這個錯誤還是我的彎彎曲曲？

我找到答案了。

那是bug ，它將在2.0-alpha2版本中修復。
