Contributions summary:Prabath primarily focused on implementing introspection support within the `carbon-identity` repository. This involved creating and modifying Java classes, specifically `OAuth2IntrospectionResponseDTO.java` and `TokenValidationHandler.java`. The changes added functionality for token validation and response generation based on the OAuth 2.0 introspection specification (RFC 7662). Furthermore, the user improved error handling within the token validation service.
