Restful Response Showing \n Instead of New Line - spring

Question

I am trying to generate a TEXT/PLAIN response for my Spring application.
When I am debugging the code, I see the string nicely formatted:
LINE1
LINE2
...
But when I see the response in Postman I see that the output is all messed up like
LINE1\nLIINE2\n....
I am not sure if the set up the controller properly or not!
Here is my Controller class:
import java.io.StringReader;
import java.util.concurrent.atomic.AtomicLong;
import java.util.logging.Logger;
import javax.ws.rs.Consumes;
import javax.ws.rs.Produces;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Unmarshaller;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
#RestController
#Configuration
#EnableAutoConfiguration
public class ConfigGeneratorController {
private final AtomicLong counter = new AtomicLong();
Logger logger = null;
#RequestMapping(value = "/configGenerator", method = {RequestMethod.POST})
#Consumes({MediaType.APPLICATION_XML_VALUE,MediaType.APPLICATION_JSON_VALUE})
#Produces({MediaType.TEXT_PLAIN_VALUE})
public ConfigGenerator configGenerator(#RequestBody String xml) {
logger = Logger.getLogger(ConfigGeneratorController.class.getName());
.
.
.
bunch of code
.
.
.
return new ConfigGenerator(counter.incrementAndGet(), String.format(actionMonitor.getGeneratedConfig().replaceAll("^\t+", "")));
}
}
actionMonitor.getGeneratedConfig() is the method that returns the string.
