Azure blob Storage: Synchronous copy of block blobs across containers within the same Azure storage account is not working

Question

I'm using the startCopy API from azure-storage java sdk version 8.6.5 to copy blobs between containers within the same storage account.

String copyJobId = cloudBlockBlob.startCopy(srcBlob, srcBlob.getProperties().getContentMD5(), true,
                                            null, null, null, null)

And I am getting the following exception -

[17:25:42.976] - [STDERR] com.microsoft.azure.storage.StorageException: The specified resource does not exist.
[17:25:42.977] - [STDERR]   at com.microsoft.azure.storage.StorageException.translateException(StorageException.java:87)

[17:25:42.978] - [STDERR]   at com.microsoft.azure.storage.blob.CloudBlockBlob.startCopy(CloudBlockBlob.java:302)
[17:25:42.978] - [STDERR]   at com.microsoft.azure.storage.blob.CloudBlockBlob.startCopy(CloudBlockBlob.java:252)

If I use the other API without sync, copy works fine -

String copyJobId = cloudBlockBlob.startCopy(srcBlob); //This works

Any idea if I am missing anything here?

Thanks in advance!!!

EDITS - Adding the screenshot of exception using the test sample code by @Bowman.

I have post the code, it seems copy with sync is no problem on my side. You can check what is the difference. — 1_1

Below code works fine on my side:

import com.microsoft.azure.storage.*;
import com.microsoft.azure.storage.blob.CloudBlobClient;
import com.microsoft.azure.storage.blob.CloudBlobContainer;
import com.microsoft.azure.storage.blob.CloudBlockBlob;


public class testbowman {

    public static void main(String[] args) throws Exception {
        String accountname = "0730bowmanwindow";
        String accountkey = "xxxxxx";
        String containername = "test";
        String source_blobname = "test1.txt";
        String sink_blobname = "test2.txt";
        StorageCredentials credentials = new StorageCredentialsAccountAndKey(accountname,accountkey);
        CloudStorageAccount account = new CloudStorageAccount(credentials);
        CloudBlobClient client = account.createCloudBlobClient();

        CloudBlobContainer container = client.getContainerReference(containername);;
        CloudBlockBlob source_cbb = container.getBlockBlobReference(source_blobname);
        CloudBlockBlob sink_cbb = container.getBlockBlobReference(sink_blobname);
        sink_cbb.startCopy(source_cbb,source_cbb.getProperties().getContentMD5(),true,null,null,null,null);
        System.out.println("This is a test.");
    }
}

And this is my pom.xml:

            <version>8.6.5</version>
        </dependency>
    </dependencies>

</project>

And this is my storage configuration:

Success copy with sync:

You can check what is the different between you can me.(By the way, startCopy(CloudBlockBlob sourceBlob) also works on my side.)
