https://github.com/apache/flink/pull/3380
I prefer to throw more detailed exceptions e.g.
`IncompatibleTypeSerializerException`, `StateAccessException` and
`StateNotFoundException`. They all are extended from `FlinkRuntimeException`.
Users can get more information from these exceptions if they catch the
exceptions.
> Throw original exception in states

> Affects Versions: 1.3.0

> Now all exception thrown in RocksDB states are converted to
> {{RuntimeException}}. It's unnecessary and will print useless stacks in the
> log.
> I think it's better to throw the original exception, without any wrapping.
