谁能帮我找出问题所在？

我的com.intel.esg.ecp.cli.Command连接到JMX，找到MXBean com.acme.AcmeManager，它应该调用createObject来创建AcmeObject。

AcmeManager 和 AcmeObject 都设计为 MXBean，我发布了没有问题。

堆栈是否意味着 AcmeObject 不确认 MXBean 标准或 AcmeManager 不确认 MXBean 标准？我是 JMX MXBean 的新手，有人可以指点我一些有用的材料吗？

谢谢

从文档

MXBean 概念提供了一种编写仅引用一组预定义类型的 MBean 的简单方法，这些类型由 javax.management.openmbean 定义。通过这种方式，您可以确保您的 MBean 将可供任何客户端（包括远程客户端）使用，而无需客户端有权访问表示您的 MBean 类型的特定于模型的类。

显然，com.acme.Acme和com.acme.AcmeObject是自定义类型，它们没有定义与 opendata 类型的转换。有关详细信息，请参阅OpenData 类型映射规则。
