Loading multiple AbstractClassEnhancePluginDefine via SPI reports an error

[noseew]

We have a need to return multiple AbstractClassEnhancePluginDefine objects of our own through the InstrumentationLoader provided by Skywalking. The difference is that the creation of the AbstractClassEnhancePluginDefine class is dynamic. I try to use bytebuddy or anonymous inner class to create, but the startup always reports an error;

It is normal for me to save the generated class instead of dynamically creating it, and then use new to create the AbstractClassEnhancePluginDefine object

Below is the error stack
