请问下，什么情况下会报这个错误：

在fastjson1时，不报错的，谢谢！

Start by inspecting JSONWriterUTF8.ensureCapacity at line 2122 and the writeStringUTF16 path shown in the stack trace. Trace how the result list reaches JSON.writeTo and FastJsonHttpMessageConverter.writeInternal, then compare the behavior with fastjson1. Done would require identifying the conditions that trigger this error and documenting or fixing the difference.
