If I try to set jclouds.provider to filesystem the following warning is shown:

[s3proxy] W 04-15 03:42:15.285 main org.gaul.s3proxy.Main:129 |::] filesystem storage backend deprecated -- please use filesystem-nio2 instead

But if I try to set jclouds.provider to filesystem-nio2 the following error happens:

Properties file must contain: jclouds.identity and jclouds.credentia

It is probably because the "new" provider is not present on this test on Main.createBlobStore.

Is adding the provider on that condition the right fix? If yes, I can create a pull request.
