我搜索了一下，找到了这篇文章 working with randoms native image，但我仍然不知道我需要做什么来解决这个问题。
似乎 quarkus 试图为 drools 创建 Random 或 SplittableRandom 的实例 class，我使用的是 optaplanner quarkus，我不使用 drools 规则引擎，我使用约束流。
有没有人在为 optaplanner quarkus 应用程序构建原生镜像时遇到同样的问题？我应该怎么做才能克服这个问题？我试过graalvm 22.0和21.3，都有同样的问题。
提前感谢您的帮助。
下面这行告诉我你的类路径有问题：
Call path from entry point to org.drools.wiring.dynamic.PackageClassLoader.writeClass(String, byte[]):
drools-wiring-dynamic 模块未设计为在本机模式下工作，需要替换为 drools-wiring-static。事实上，optaplanner-quarkus 模块会为您完成所有这些工作。
您使用的是 optaplanner-quarkus 而不是 optaplanner-core？堆栈跟踪告诉我你可能不是。如果是，我建议您找出 drools-wiring-dynamic 依赖项的来源，然后将其删除。
另一个问题来源可能是您试图在本机模式下使用约束 DRL。这不受支持，并且会因一个或另一个异常而失败。在本机模式下，您有三种约束选择 - 约束流、Java 增量或 Java 简单。
