---------------------------------

             Summary: (SASL/OAUTHBEARER) multiple applications in one JVM process, only the first started app can consume messages
                 Key: KAFKA-14102
                 URL: https://issues.apache.org/jira/browse/KAFKA-14102
             Project: Kafka
          Issue Type: Bug
          Components: clients, KafkaConnect
    Affects Versions: 3.0.1
            Reporter: Shuo Chen


We have 2 web applications (A and B) will consume messages from the same Kafka Server,  so they have the same configurations:

 
{code:java}
security.protocol=SASL_SSL
sasl.mechanism=OAUTHBEARER
sasl.jaas.config=org.apache.kafka.common.security.oauthbearer.OAuthBearerLoginModule required; sasl.login.callback.handler.class=MyOauth2AuthenticateCallbackHandler jaas.enabled=true{code}
 

 

A and B deployed together in one Tomcat server (means they are in JVM process), startup  sequential is A -> B,  then we find B cannot consume the message with following exception:
