ClassCircularityError: java/lang/WeakPairMap$Pair$Weak in JUnit5, Springboot, Pact Project in Debug Mode

Question

我们有一个使用 JUnit 5 和 Pact 的 spring 引导项目。 我们使用的是 OpenJDK 17。当我们运行 JUnit 5 测试时，我们没有遇到任何问题，但是当我们想要调试它们时，我们遇到了以下问题。

注意：我尝试了许多版本的 JUnit Jupiter 和 Pact 依赖项，但无法解决问题。

当我们删除 pact junit5 消费者和提供者依赖项时，调试工作正常。

我还在 IntelliJ 中尝试了 Async Stack Traces -> Instrumenting Agent 选项开/关，但它没有解决任何问题。

任何帮助深表感谢。

我在调试测试时遇到了这个问题。 当我运行它们时，我没有任何问题。 经过长时间调试 session，我发现 pact core model 和 ktor 库导致了这个问题，下面的依赖设置工作正常，但我需要这些库来运行合同测试。

有谁知道如何解决这个问题？ 谢谢。

经过长时间的调试，pom.xml 中的以下配置有效。 ktor 库在我们的 Springboot、webflux、junit5、openJDK17 项目中造成冲突。
