Storage.copy not failing on source (meta)generation mismatch

[mziccard]

The following code:

Storage.CopyRequest req = new Storage.CopyRequest.Builder()
  .source(bucket, sourceBlobName)
  .target(destinationBlob)
  .sourceOptions(Storage.BlobSourceOption.generationMatch(42L))
  .build();
storage.copy(req);

Is not throwing an exception if the source blob generation is not 42.

Is this an issue with the server-side stuff not returning a fail? (Is it picking "the closest one to 42"?) Or is this in our code?

@jgeewax It's an issue with our code, we are not sending the correct parameters, I am about to submit a fix. Server-side stuff is checking for exact match.
