Hi! The `PropertiesUtil.getBoolean` currently only exists in `1.3-SNAPSHOT`. The method was added along with one of the Kafka consumer changes recently.
Generally, you should always use matching versions of the Flink installation and the library, otherwise these kind of errors can always be expected.

Thanks in anticipation!
