JsonMappingException问题,求大神解答

求大神解答:
从服务器获取了一段json,现在要转成bean.

上代码:

public static Object Json2Gson( Class<?> clz,String jsonString) throws IOException {
 ObjectMapper objectMapper = new ObjectMapper();
 objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
 return objectMapper.readValue(jsonString, clz);
 }

但是解析报错了:

cn.serviceforce.cssdk.jackson.databind.JsonMappingException:
 Conflicting setter definitions for property "imagePath": 
 android.graphics.Bitmap#setImagePath(1 params)
 vs android.graphics.Bitmap#setImagePath(1 params)

什么原因呢,求大神解答啊
