Current Behavior

Bucket.getOwner() in the Java API is not able to parse the new size of the owner's name. A null pointer exception is raised.

Expected Behavior

You should see an object of the Owner in the Java in version 1.4.0 while a crash with a null pointer exception in localstack version 2.0.0

How are you starting LocalStack?

With a docker-compose file

Steps To Reproduce

1. To replicate, use the following docker-compose file, twice, once with version 1.4.0, and the other with 2.0.0

Each time run the following command:
2. awslocal --endpoint="http://localhost:8010" s3api list-buckets

In the first you should get

{
    "Buckets": [],
    "Owner": {
        "DisplayName": "webfile",
        "ID": "bcaf1ffd86f41161ca5fb16fd081034f"
    }
}

In the second you should get

{
    "Buckets": [],
    "Owner": {
        "DisplayName": "webfile",
        "ID": "75aa57f09aa0c8caeab4f8c24e99d10f8e7faeebf76c078efc7c6caea54ba06a"
    }
}

Notice the difference in the large string in the ID.

3. create a new bucket: awslocal --endpoint="http://localhost:8010" s3 mb s3://mybucket
4. Use java API to get the owner of the bucket which should map to the behavior here.

Docker file:

version: '3.0'
services:
  localstack:
    container_name: localstack
    image: localstack/localstack:2.0.0 # or switch to 1.4.0

    ports:

Environment
