Kafka Consumer InterruptedException during pipeline validation

Scenario:

1) Start SDC

2) Import pipeline with 3 stages: Kafka multi source origin -> Groovy Evaluator -> ToError

3) Perform any update of Groove Script in Groovy Evaluator.

Observation:

In logs I can see exceptions related to KafkaMultiSource thread being interrupted. Also I can see that Kafka related threads are being created and deleted shortly. But some threads (kafka-coordinator-heartbeat-thread-* in my case) stay alive which is weird since I didn't even start my pipeline.

For me it looks like after Groovy script change SDC performs pipeline validations which leads to Kafka consumer creation (to check topic existence) and deletion. Since it happens pretty fast some threads do not stop properly.
