S3Object.size() return type is Integer, not Long

[trawicjc]

In AWS Java SDK v1, S3ObjectSummary objects returned by AmazonS3.listObjectsV2 return object sizes as long. In v2, S3Object objects returned by S3Client.listObjectsv2 return object sizes as Integer. How do I get correct object sizes in v2 when objects are larger than 2GB?

Expected Behavior

S3Object.size() returns Long

Current Behavior

S3Object.size() returns Integer

Possible Solution

Modify S3Object.size() to return Long such that it accommodates objects larger than 2GB.

Steps to Reproduce (for bugs)

Call S3Client.listObjectsV2(request) and observe the type of the size property in the result contents array.

Context

Attempting to port object size analysis code from SDKv1 to SDKv2 to exploit the simpler API.

We are discussing internally on the right way to fix - make a breaking change or deprecating the API. We will update the issue once the decision is made and fix is ready.
