The class
Code:
org.springframework.http.converter.json.MappingJacksonHttpMessageConverter
from Spring 3.2.1 version is now incompatible to Jackson FasterXML 2.1.x versions. I found following incompatibilities:

1. Incorrect imports. Current Spring implementation uses following imports:

Code:
import org.codehaus.jackson.JsonEncoding;
import org.codehaus.jackson.JsonGenerator;
import org.codehaus.jackson.JsonProcessingException;
import org.codehaus.jackson.map.ObjectMapper;
import org.codehaus.jackson.map.SerializationConfig;
import org.codehaus.jackson.map.type.TypeFactory;
import org.codehaus.jackson.type.JavaType;
Whereas, as per new Jackson FasterXML library, these should be:
Code:
import com.fasterxml.jackson.core.JsonEncoding;
import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.JavaType;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import com.fasterxml.jackson.databind.type.TypeFactory;
2. Following method is using a method which is removed from Jackson library.
Code:
protected JavaType getJavaType(Type type, Class<?> contextClass) {
   return (contextClass != null) ? 
    TypeFactory.type(type, TypeFactory.type(contextClass)) :
                    TypeFactory.type(type);
}
In the new Jackson FasterXML 2.1.3 version, the method
Code:
TypeFactory.type
is removed. Instead of this, following should be used:
Code:
protected JavaType getJavaType(Type type, Class<?> contextClass) {
   final TypeFactory typeFactory = this.objectMapper.getTypeFactory();
   return (contextClass != null) ? typeFactory.constructType(type, contextClass) : typeFactory.constructType(type);
}
3. Spring code is using enums which are removed from Jackson library. e.g.

SerializationConfig.Feature.INDENT_OUTPUT is replaced by
SerializationFeature.INDENT_OUTPUT

4. Spring code is using deprecated method to create JSON factory in the method writeInternal.

Code:
JsonGenerator jsonGenerator = this.objectMapper.getJsonFactory().createJsonGenerator(outputMessage.getBody(), encoding);
The method getJsonFactory() is deprecated and the new method is getFactory()

My question is, will Spring fix these in its library or I should write my own message converter.

Thanks,
