加上最后的静态常量全球下课“无法初始化全局对象”错误('Cannot init the Gl

我使用的播放框架2.2.3与Java。

我只是添加一个常数我的全局类：

public static final String VERSION = play.application().configuration().getString("application.version");

然后，我得到这个错误：

我的应用程序之前，是工作的罚款。如果我把这个常量在其他任何类，我的应用程序工作正常。只有当我把它放在全球我得到这个错误。任何帮助吗？

由于在这个问题指出，如果你想在应用程序启动时访问配置，你应该使用OnStart方法。
