Neptune exporter tool to S3 running on Windows EC2

Hi, I'm running neptune exporter jar tool from a command prompt of a Windows EC2 istance. Everithing is ok until the time the tool has to write on the target s3 Bucket. The tool seems to add a S3 suffix with the Windows path separtor so there is an error. This is the neptune export tool error:

Caused by: java.net.URISyntaxException: Illegal character in path at index 44: s3:///\neptune-export.

The S3 target bucket is setted in the path parameter as "outputS3Path":"s3:///". The neptune-exporter tool adds **\neptune-export** instead of **/neptune-export** .

So i have two questions:

Is the neptune exporter tool not a Windows tool or there is a workround to escape the problem running on Windows prompt?
The copy to S3, from local folder, (**root-path** ) is at the end of all export process or there are more than one phase ?
Thank you

Reproduce the neptune-exporter command on a Windows EC2 instance using the reported outputS3Path value, then trace how the target S3 URI is assembled before the copy phase. Done means the export can write to the S3 bucket from Windows without an invalid path separator, with the export phases clarified.
