Blocking Call on DigestAlgorithm #6590
Description
Describe the bug
Hello,
While using BlockHound to detect blocking calls on our service, we found out a blocking call on https://github.com/aws/aws-sdk-java-v2/blob/master/core/checksums/src/main/java/software/amazon/awssdk/checksums/internal/DigestAlgorithm.java#L55 . It seems this is related to a recent change in this class (c137348) that introduced a LinkedBlockingDeque.
Regression Issue
- Select this option if this issue appears to be a regression.
Expected Behavior
The Async version of the SDK shouldn't block threads.
Current Behavior
Due to the internal code of LinkedBlockingDeque, the modified DigestAlgorithm blocks.
Reproduction Steps
Any HTTP request will trigger this issue, example the Async SDK for DynamoDB (GetItem).
Possible Solution
Use ConcurrentLinkedDeque or ThreadLocal perhaps.
