我有一个可执行的 jar，它是用 java 6 编译的，在这个项目中，datanucleus 用作 ORM（旧版本，1.1.6）。
jar 在 java 6、7、8 上运行良好，但在 9 (10) 下运行良好：运行它我在各种类上得到很多或类似这样的错误：
javax.jdo.JDOFatalUserException: A property named javax.jdo.PersistenceManagerFactoryClass must be specified, or a jar file with a META-INF/services/javax.jdo.PersistenceManagerFactory entry must be in the classpath, or a property named javax.jdo.option.PersistenceUnitName must be specified.

MyClass我得到错误的所有类都是通过数据核增强器增强的类。
阅读周围的东西我试过这个：
java --illegal-access=permit --add-opens java.base/java.lang=ALL-UNNAMED -jar MyJar.jar
但同样的结果。
我只是想用 java 9 运行这个可执行 jar，而不是用 java 9 重新编译代码。
我知道仅仅一条错误消息很难给出答案，但有人有一些提示吗？
代码很旧，使用的库也很旧，但它在 java 8 上运行良好，这是导致问题的 java 9 上发生的变化。
更新：根据要求更新了完整的堆栈跟踪
