This caused the following exception to be thrown. {code} org.apache.kafka.common.errors.SerializationException: Can't convert value of class [B to class org.apache.kafka.common.serialization.BytesSerializer specified in value.serializer {code} This doesn't provide much detail because it strips the ClassCastException. It made figuring this out much more difficult. The real value was the inner exception which was: {code} [B cannot be cast to org.apache.kafka.common.utils.Bytes {code} We should include the ClassCastException. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
