DynamoDBLocal 1.20.0 does not work with Spring Boot 3 (ClassNotFoundException: javax.servlet.ServletInputStream)

[mgr32]

Describe the bug

DynamoDBLocal-1.20.0.jar (com.amazonaws:DynamoDBLocal:1.20.0) has references to javax.servlet, making it impossible to use it with Spring Boot 3 (which requires migration to Jakarta EE 10).

Expected Behavior

Instantiating LocalDynamoDBRequestHandler in presence of Spring Boot 3 should not throw ClassNotFoundException exception.

Current Behavior

Tryng to instantiate LocalDynamoDBRequestHandler class throws the following exception:

Reproduction Steps

2. Add com.amazonaws:DynamoDBLocal:1.20.0 dependency as described in the instructions
3. Try to instantiate LocalDynamoDBRequestHandler class.

Example code that reproduces the issue: https://github.com/mgr32/dynamodblocal-spring-boot-3

Hi @mgr32

DynamoDB Local is not maintained by the AWS SDK for Java team. I'll pass your report forward to the DynamoDB Local team and update here when I hear back.

[debora-ito]

The DynamoDB Local team replied, and currently there's no plans to fix this behavior.

Closing this, as there's nothing pending on the Java SDK team.
