@steve-todorov did you already find the time to look into this?

@oeph Apologies was very busy the past couple of months and dropped the ball on this. I'll be doing some dependency updates this week so I'll check this one too.

@steve-todorov any updates on this?

[steve-todorov]

@oeph i was able to do some maintenance tasks last week and had a quick peek at this PR too. The tests are still failing which means there's a problem with the proposed change. I wasn't able to go through a full debug session to pinpoint the exact cause but might be related to the FileStores where the bucket is also needed or a related part.

@kxm-kstlr Thanks for raising the PR and for your patience.

I finally had some time to look into this in more depth.

Long story short -- the listBuckets endpoint provides metadata information about each bucket such as the createdDate. This matters, because that information is being used when implementing the Java NIO interfaces.

At the time of writing this, there is simply no way to fetch this other than pulling it from the listBuckets endpoint.
Here's some of the relevant documentation:

• Bucket object
• List Buckets response

This is partially why the tests in the CI were failing as well.

Unfortunately we will have to close this PR and the task as "wont fix", simply because of AWS S3 Rest API limitations.

P.S. We're open to revisit this should the AWS S3 API change or if another way becomes available.
