Status: Resolved | Priority: Major | Resolution: Fixed

Affects Version/s: 3.3.0

We are seeing the following two kinds of intermittent exceptions when using S3AInputSteam:

1.

 and
 [https://forums.aws.amazon.com/thread.jspa?threadID=83326], we got a solution that has helped us, would like to put the fix to the community version.

The problem is that S3AInputStream had a short-lived S3Object which is used to create the wrappedSteam, and this object got garbage collected at random time, which caused the stream to be closed, thus the symptoms reported.

[https://github.com/aws/aws-sdk-java/blob/1.11.295/aws-java-sdk-s3/src/main/java/com/amazonaws/services/s3/model/S3Object.java#L225] is the s3 code that closes the stream when S3 object is garbage collected:

Here is the code in S3AInputStream that creates temporary S3Object and uses it to create the wrappedStream:
{code:java}
   S3Object object = Invoker.once(text, uri,
        () -> client.getObject(request));

    changeTracker.processResponse(object, operation,
        targetPos);
    wrappedStream = object.getObjectContent();
