      Description

      I have a simple kafka-streams example which just reads in some transactions and writes them back out again.

      https://github.com/jamii/streaming-consistency/blob/c1f504e73141405ee6cd0c7f217604d643babf81/kafka-streams/src/main/java/Demo.java

      This works fine and I see the right output in 'accepted_transactions'.

      If I uncomment the left join at line 58, then not only do I not get any output for the left join, but I don't get any output in 'accepted_transactions' either.
