---------------------------------------

             Summary: Kafka Streams crashes with UnsupportedOperationException
                 Key: KAFKA-19171
                 URL: https://issues.apache.org/jira/browse/KAFKA-19171
             Project: Kafka
          Issue Type: Bug
          Components: streams
    Affects Versions: 4.0.0
            Reporter: Matthias J. Sax
             Fix For: 4.1.0, 4.0.1


We observed the following stack trace in our soak cluster
{code:java}
Caused by: java.lang.UnsupportedOperationException
at java.base/java.util.AbstractCollection.add(AbstractCollection.java:251)
at 
org.apache.kafka.streams.processor.internals.TaskManager.closeTaskClean(TaskManager.java:959)
at 
org.apache.kafka.streams.processor.internals.TaskManager.handleTasksPendingInitialization(TaskManager.java:517)
 {code}
Looks like an regression bug: we are passing in an immutable Set.
