Java Hibernate工具-NullPointerException-TablePropertiesBlock

我想开发一个应用程序的小型原型。我已经在MySQL 5.6上创建了一个数据库。他们只有两个表——一个从mastertable到childtable的引用（这就像一个简单的原型）。所有表都有一个Id列

我使用Eclipse4.4.1（Windows7x64上的x86-德语）、Hibernate4.3.8、HibernateTools4.0.0（最终版本）

我可以在找到的turtorials中创建所有步骤（创建hibernate.cfg.xml、console config和hibernate.reveng.xml）

现在我想定制我的reveng.xml。我将配置列的设置。但是我不能将它们放在带有“Tables&Column”对话框的reveng.xml中。我使用“添加”按钮，表格显示并可以选择。但是如果我按下“ok”按钮，选择将不会发送到xml

我做错了什么？我忘了什么吗

下面是Eclipse的错误日志详细信息：

Unhandled event loop exception
