"putObjectFromStream" example fails on current version - S3 streaming uploads

### Describe the bug

Hi,

Both of the examples at https://docs.aws.amazon.com/code-library/latest/ug/s3_example_s3_Scenario_UploadStream_section.html
and the example at https://github.com/awsdocs/aws-doc-sdk-examples/blob/main/javav2/example_code/s3/src/main/java/com/example/s3/async/PutObjectFromStreamAsync.java (which is the same as the first example at the former link) are failing on the current version of the SDK

The error given is:

```
Exception in thread "main" java.util.concurrent.CancellationException: subscription has been cancelled.

```

I have tested this on windows and Mac with the following versions, same error:

Repro 1 versions:

Windows 11
"java --version" prints:

### Regression Issue

- [x] Select this option if this issue appears to be a regression.

### Expected Behavior

Expected the stream to be uploaded to S3

### Current Behavior

The error given is:

```
Exception in thread "main" java.util.concurrent.CancellationException: subscription has been cancelled.

### Reproduction Steps

Run the example code at https://github.com/awsdocs/aws-doc-sdk-examples/blob/main/javav2/example_code/s3/src/main/java/com/example/s3/async/PutObjectFromStreamAsync.java

### Possible Solution

_No response_

### Additional Information/Context

_No response_

### AWS Java SDK version used

2.29.21

### JDK version used

openjdk 17.0.14, openjdk 21.0.2 2024-01-16

### Operating System and version

Windows 11, Mac

Run the reproduction from PutObjectFromStreamAsync.java in the linked awsdocs example with the reported SDK and JDK versions, and compare it with the S3 streaming-upload documentation example. Trace the cancellation reported in the stack trace; done means the example completes and the stream is uploaded to S3 without the CancellationException.
