S3Client fails with EOFException when executing HeadObjectRequest for gzip encoded object

[productivityindustries]

Describe the bug

I am trying to execute a HeadObjectRequest for objects stored in S3. All objects are compressed and do have Content-Encoding: gzip.

Expected Behavior

Just head info's are returned - and no exception is thrown.

Current Behavior

This stacktrace is logged:

@productivityindustries it's weird you're seeing this with the sync client, the issue was only seen before in async client.

I was not able to reproduce. Can you turn on the wire logs and provide them? Please make sure to redact or remove any sensitive data.

Additional info: it's breaking only when using software.amazon.awssdk:url-connection-client, instead of apache-client.

I was able to produce the wire logs by adding javax.net.debug=all, but they are very verbose, as they include also SSL handshake. Do you still need them?

Ok this was an important difference, I'll try to repro again.

[debora-ito]

I can reproduce it now, confirming as a bug.

Is there any news on this one?
I am using SDK version 2.17.196 and having this issue.
Using headObject with S3 client with software.amazon.awssdk:url-connection-client
Thanks.

It's more than 1 year now we are waiting for a fix. Is that hard to find a solution?
