[Engelberg]

I get the following error when I try to run Challenge 6_0's tests:

I wasn't able to reproduce this one. What Git SHA of learn-onyx are you using, which version of Java, and which OS? Seems environmental since this would be the first challenge that uses BookKeeper and RocksDB internally.

[Engelberg]

Cloned the git repository two nights ago, says I'm still current with master.
Java 1.8.0_66
Windows 10

[Engelberg]

git show head
commit 2ecc156

[MichaelDrogalis]

Ah, I wouldn't be surprised if it's because of Windows. Not sure if RocksDB or BookKeeper place nice with that OS, and we don't officially support Windows. Sorry. :(

[Engelberg]

Yeah, seems to be a problem with RocksDB. It's looking for a dll (librocksdbjni-win64.dll), but there doesn't seem to be any place on the web from which to download it.

[MichaelDrogalis]

Closing, Windows isn't on the radar.
