Kafka-jms-client

We want to use the kafka-jms-client java library with our own apache kafka cluster.

However accdg to

https://docs.confluent.io/3.2.0/clients/kafka-jms-client/docs/index.html#requirements

“To use the kafka-jms-client you must have a current Confluent Enterprise subcription.”

We need to pay confluent license just to use the library?

Please clarify

What’s not clear? It’s also for support, Confluent Platform Licenses | Confluent Documentation.
