Description

The name of the state backend in the configuration file ist converted to lower-case (see https://github.com/eBay/Flink/blob/master/flink-streaming-java/src/main/java/org/apache/flink/streaming/runtime/tasks/StreamTask.java#L587).

Therefore, the class cannot be found, and the state backend (e.g., RocksDB) is not loaded properly (see https://github.com/eBay/Flink/blob/master/flink-streaming-java/src/main/java/org/apache/flink/streaming/runtime/tasks/StreamTask.java#L603).
