Looking at the stack, it's {{new Path("")}} which is failing

> Key: HADOOP-13517
> URL: https://issues.apache.org/jira/browse/HADOOP-13517
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs/s3
> Affects Versions: 3.0.0-alpha2
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Minor
>
> while doing s3a tests against trunk, one of the S3n tests,
> {{TestS3NContractRootDir.testRecursiveRootListing}} failed.
> This may be a failure of recursive listing of an empty root directory; it's
> transient because of deletion inconsistencies means the problem doesn't
> always surface
