我必须在java 8环境中编译并运行seam-2.2.2应用程序。一切都很好，除了缝线身份管理。这似乎与seam-2.2.2的Drools有关
当我在java 8环境中运行seam应用程序时，会引发以下异常org.jboss.seam.InstantiationException：无法实例化Seam组件：org.jboss.seam.security.ruleBasedPermissionResolver
从应用程序中排除drools，不再例外。接缝应用程序正常工作。 java 5环境中没有引发异常。
知道如何解决这个问题吗？

答案 0 :(得分：1)
我认为这里发生的事情是来自seams（和你的应用程序）的一些Java代码是使用java 8编译器编译的。然后调用org.drools.compiler.PackageBuilder来编译一些DRL。最终，这将调用Java编译器来编译从DRL生成的Java代码。为此，通过Eclipse调用Java编译器，当遇到（由于import语句）由Java 8编译的类时，此编译器不满意。
因此，这是修复Eclipse和Java安装的问题。
有一种方法可以配置Drools使用的Java编译器，但通常使用默认设置（即Eclipse）可以很好地工作。
