> {code}
> The Environment.getJniLibraryName method has branches for different operating systems, and is missing a separate branch for windows. While this is resolved in the RocksDB Github repository, it is not in the latest release (4.2).
> This problem causes several test in RocksDBStatebackendConfigTest and all tests in RocksDbStatebackendTest to fail. RocksDBAsyncKVSnapshotTests simply deadlock aswell.
> I propose disabling all tests when run on Windows.
