Summary of Changes

Hello @kabir, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

I've refactored the GrpcHandler class to remove its direct dependency on CDI (Contexts and Dependency Injection), making it a more flexible and reusable utility. This change promotes a cleaner separation of concerns by moving dependency provision to concrete subclasses, as demonstrated by the updated QuarkusGrpcHandler.

Highlights

• Decoupling GrpcHandler from CDI: The GrpcHandler class is now an abstract class, shedding its @ApplicationScoped annotation and direct @Inject fields, promoting a more decoupled design.
• Dependency Provision via Abstract Methods: Dependencies like AgentCard, RequestHandler, and CallContextFactory are now accessed via new protected abstract getter methods within GrpcHandler, allowing subclasses to provide them.
• Quarkus-specific Implementation: QuarkusGrpcHandler has been updated to inject these dependencies in its constructor and provide them through the overridden abstract methods, serving as a concrete implementation for the abstract GrpcHandler.
• Test Class Updates: Test classes, specifically GrpcHandlerTest, now utilize a new TestGrpcHandler subclass to properly instantiate and test the refactored GrpcHandler, ensuring testability of the new design.
• Configurable Test Port: The AgentCardProducer in test utilities now supports configuring the agent card's URL port via a system property, enhancing test environment flexibility.

Code Review

This pull request successfully refactors GrpcHandler to remove its dependency on CDI, making it an abstract utility class. This is a solid architectural improvement that increases modularity and testability. The changes are consistently applied, with a new QuarkusGrpcHandler for the CDI-based environment and an inner TestGrpcHandler for unit testing. My feedback includes a few minor suggestions to further improve code quality.

Code Review

This pull request refactors GrpcHandler to be an abstract class, removing its direct dependency on CDI. This is a good architectural improvement, making the handler more of a reusable utility. The dependencies are now supplied by concrete subclasses through abstract methods, as demonstrated by the new QuarkusGrpcHandler for CDI environments and a TestGrpcHandler for tests. The changes are well-executed. I have a few minor suggestions to improve code consistency.
