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

Thanks for the quick fix!

Sorry about the links to the wrong repository in the original description. For the record,
here are the correct links to the mentioned locations in the code (at the time of the submission):

https://github.com/apache/flink/blob/0dac7ad00a25c4b038b57009f41f5512f8ce73c3/flink-streaming-java/src/main/java/org/apache/flink/streaming/runtime/tasks/StreamTask.java#L755

>             Project: Flink
>          Issue Type: Bug
>          Components: State Backends, Checkpointing
>    Affects Versions: 1.1.2
>         Environment: Debian Linux and Mac OS X
>            Reporter: Florian Koenig
>            Assignee: Stephan Ewen
>            Priority: Blocker
>             Fix For: 1.2.0, 1.1.3

> 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).
