Issue with Avro generated classes: camelCase and snake_case combo in one class causes UnrecognizedPropertyException

[fcpunk]

By the look of it starting from v2.12 something changed in ObjectMapper implementation and the code below stopped working:

import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;

public class Sample {
	private String snake_case;
	private String camelCase;

	public String getSnakeCase() {
		return snake_case;
	}

	public void setSnakeCase(String snake_case) {
		this.snake_case = snake_case;
	}	
	
	public String getCamelCase() {
		return camelCase;
	}
	
	public void setCamelCase(String camelCase) {
		this.camelCase = camelCase;
	}
	
	@org.junit.jupiter.api.Test
	public void test() throws JsonProcessingException {
		ObjectMapper objectMapper = new ObjectMapper();
		objectMapper.readValue("{\"snake_case\": \"sample data 1\",\"camelCase\":\"sample data 2\"}", Test.class);
	}
	
}

MixIn and annotations are not an option for generated classes. This is just a simple example, in my case class has hundreds of fields and is generated from an Avro schema. I have no control over generation of the getters/setters which confuses Jackson.

Is there any way to handle this use case?
