{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.
