Thanks a lot! I was able to set an object as a property and get this to work. It also turns out that KafkaProducer is thread safe, so I only need to create one instance in my setUp thread group.
However - this violates the contract of the Properties class, which should have only strings as keys and values ( https://docs.oracle.com/javase/8/docs/api/java/util/Properties.html). Not sure it's a proper thing to do.
