spring kafka how to configure two jaas of different kerberos

I have spring boot application, which is recives data over rest, based on some business logic I need to forwaard the data to two different kafka cluster which have their own kerberos keys menttioned jaas file.

I have written two different producer Instance with below properties in their different object instances.

@Service
public class EventProducer {
    private Logger logger = LoggerFactory.getLogger(EventProducer.class);
 
    
    Producer<String, String> kafkaProducer = null;

    @Autowired
    public Producer<String, String> createProducer() {
        if (kafkaProducer == null) {
            Properties props = getKafkaConfig();
         props.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, "Cluste_1_hostaddress:9092");
         props.put(ProducerConfig.CLIENT_ID_CONFIG,"usertest");

         props.put(ProducerConfig.ACKS_CONFIG, "all");
         props.put(ProducerConfig.RETRIES_CONFIG, "3");

         props.put(ProducerConfig.BUFFER_MEMORY_CONFIG, 33554432);
         props.put(ProducerConfig.BATCH_SIZE_CONFIG, 1600);

         System.setProperty("javax.security.auth.useSubjectCredsOnly", "true"); 
         System.setProperty("java.security.auth.login.config", "/home/user/clusrter_1_jaas.conf);   
         
         props.put("security.protocol", "SASL_PLAINTEXT");
         props.put("kafka.cluster.SecurityProtocol",PLAINTEXTSASL);
         props.put("sasl.kerberos.service.name",  "kafka"); 
         props.put("sasl.kerberos", "sasl.kerberos.service.namekafka");     
         props.put("security.inter.broker.protocol", "SASL_PLAINTEXT");
         props.put("sasl.mechanism.inter.broker.protocol", "PLAIN");
         props.put("sasl.enabled.mechanisms", "PLAIN");
         props.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, StringSerializer.class.getName());
             
         kafkaProducer = new KafkaProducer<String, String>(props);
        }
        return kafkaProducer;
    }
 
}

Second producer

@Service
public class MovementProducer {
    private Logger logger = LoggerFactory.getLogger(MovementProducer.class);
    
    Producer<String, String> kafkaProducer = null;

    @Autowired
    public Producer<String, String> createProducer() {
        if (kafkaProducer == null) {
            Properties props = getKafkaConfig();
         props.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, "Cluste_2_hostaddress:9092");
         props.put(ProducerConfig.CLIENT_ID_CONFIG,"usertest");

         props.put(ProducerConfig.ACKS_CONFIG, "all");
         props.put(ProducerConfig.RETRIES_CONFIG, "3");

         props.put(ProducerConfig.BUFFER_MEMORY_CONFIG, 33554432);
         props.put(ProducerConfig.BATCH_SIZE_CONFIG, 1600);

         System.setProperty("javax.security.auth.useSubjectCredsOnly", "true"); 
         System.setProperty("java.security.auth.login.config", "/home/user/clusrter_2_jaas.conf);   
         
         props.put("security.protocol", "SASL_PLAINTEXT");
         props.put("kafka.cluster.SecurityProtocol",PLAINTEXTSASL);
         props.put("sasl.kerberos.service.name",  "kafka"); 
         props.put("sasl.kerberos", "sasl.kerberos.service.namekafka");     
         props.put("security.inter.broker.protocol", "SASL_PLAINTEXT");
         props.put("sasl.mechanism.inter.broker.protocol", "PLAIN");
         props.put("sasl.enabled.mechanisms", "PLAIN");
            props.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, StringSerializer.class.getName());
         
            kafkaProducer = new KafkaProducer<String, String>(props);
        }
        return kafkaProducer;
    }
 
}

When I start this as two service with enabling only producer instance it works, but when I enable both instance in a single jar only one producer works and other gets authentication issues.

I feel this is due to System.setProperty("java.security.auth.login.config","") , since it is global system variable so it overrides when i use both in single process, so only one works.

So is there any way to solve this issue other than starting a two process. I have only one spring service and should be able to produce to both different kafka cluster ..
