I am attempting to use OCI Instance Principal authorization with Kafka Producer API to produce message to a OCI streams endpoint. I am referring to the documentation provided here - https://docs.public.oneportal.content.oci.oraclecloud.com/en-us/iaas/Content/Streaming/Tasks/kafkacompatibility_topic-Configuration.htm
I run into the below issue that seems to indicate that the Jersey client instance is closed even as the attempt is being made to call the metadata service endpoint.

The container that executes this code is running within an OCI compute instance. Can I get help to understand the cause of this issue?
