Issue/Introduction

Trying to setup Kafka recorder getting the following error when trying to start.   

java.util.ConcurrentModificationException: KafkaConsumer is not safe for multi-threaded access

 

Environment

Release : 10.5.1

Component : CA Service Virtualization

Resolution

I removed jars provided by customer and created different topic for Response and Request and I am able to start the recording.

From Webex recording it looks like customer is using same topic(SV_TOPIC_IMS_Lab) for Request and Response.

Please advice him to use the different topics for request and response like SV_TOPIC_IMS_Lab_Request and SV_TOPIC_IMS_Lab_response.
