You're right that the problem isn't the path length.

This issue is another incarnation of people passing a Flink {{Path}} to the java {{File}} API. In our RocksDB related code we take Files, convert them to paths, and then convert them to Strings before passing them to Rocks, when instead we should pass the path returned by the file directly.

> The {{RocksDbStateBackendTest}} fails on windows when incremental checkpoint is enabled.
> Based on the exception i guess the file name is just simply too long:
