我想对用GraalVM本机映像生成的SubstrateVM本机映像进行基准测试，但是如果它不是需要运行JVM的后备映像，则无法生成它。
我知道其中涉及到很多反射，所以我编写了一个Reflection.json配置文件，在其中指定了受影响的类，但是这并没有达到我的预期。
现在，我仅想对BubbleSort进行示例测试，因此我尝试使用本机图像对其进行编译，并使用错误消息使用通配符编写了Reflection.json配置文件。我在这里找到了一个示例：https://github.com/oracle/graal/blob/master/substratevm/REFLECTION.md#manual-configuration
这是我尝试从我的基准.jar中编译本机映像时收到的错误消息的一部分：

我希望它能够在配置文件中定义受影响的类时进行编译。 我执行此操作以生成图像： native-image -jar Benchmarks.jar H：ReflectionConfigurationFiles = reflection-config.json
