Description

Kafka's startup can fail if there is a trailing or leading whitespace for a configuration value. This fix makes it more tolerant towards cases where a user might accidentally add a trailing or leading whitespace in ACL configuration.

ERROR [KafkaServer id=3] Fatal error during KafkaServer startup. Prepare to shutdown (kafka.server.KafkaServer)

java.lang.IllegalArgumentException: For input string: "true "
