ObjectMapper add Module "jackson-module-afterburner" java.lang.IllegalStateException: Multiple definitions of method getBody found

[bxvs888]

result :

Jackson version: 3.0.1 fail

interface A:

public interface A<T> {

	 T getBody();
}

implements

public class MD implements A<String> {

	private String body;
	/**
	 * @return
	 */

	@Override
	public String getBody() {
		return body;
	}
}

convert toJSON:

	public static void main(String[] args) {


		MD md = new MD();

		ObjectMapper objectMapper =
				JsonMapper.builder()
				 .addModule(new AfterburnerModule())
					 .build();
		String json = objectMapper.writeValueAsString(md);
		System.out.println(json);

I assume this would also fail in 2.x (like 2.20.0)? (not sure if it'd be easy to check -- I can try reproduce)

[cowtowncoder]

As per #315, works on 2.x...

[cowtowncoder]

Hmmh. Can not reproduce in 3.x either, see:

[cowtowncoder]

Need a reproduction of failure: my attempt to use given example not successful.
