Today, Oracle is pleased to announce Graal Dev Kit for Micronaut 5 (GDK), based on the open source Micronaut Framework 5, with enhanced Oracle AI Database integration, refreshed multicloud capabilities, and extended support for existing Micronaut 4.10 users through July 2027.
The GDK is Oracle’s distribution of a curated set of open-source Micronaut® framework modules and their dependencies, built from source with build provenance attestation and a software bill of materials to enhance security. Optimized for ahead-of-time compilation with GraalVM Native Image, the GDK enables you to build portable, cloud-native Java microservices with fast startup and lower resource usage, helping reduce compute costs.
Built on Micronaut 5
Based on Micronaut 5, this release updates the framework APIs, libraries, and developer tooling.
Key platform updates include:
- Java 25 baseline with Oracle GraalVM 25.0.3
- JSpecify nullability annotations
- Enhanced configuration and JSON Schema-based configuration validation
- Improved serialization capabilities
- Micronaut Jackson Databind updates to Jackson 3
These enhancements continue Micronaut’s focus on developer productivity, fast startup, and efficient deployments. Recent releases, including Micronaut Framework 5.0.1 and Micronaut Framework 5.0.2, further strengthen the platform with stability and security fixes.
Simplifying Oracle AI Database Applications
A key highlight of this release is that the GDK makes it easier to use the latest Oracle AI Database capabilities through deeper integration with Micronaut Data.
Highlights include:
- Oracle Spatial and geospatial mapping support
- Oracle Database VECTOR type and Oracle AI Vector Search support
- Oracle JSON Relational Duality View support
- Enhanced observability with OpenTelemetry-based tracing
These capabilities make it easier to build intelligent applications that combine transactional, JSON, vector search, and geospatial workloads on Oracle AI Database while providing greater visibility into application and database interactions.

Cloud-Native Development Across OCI, AWS, Azure, and GCP
The GDK continues to provide a curated multicloud development experience with integrations for Oracle Cloud Infrastructure (OCI), Amazon Web Services (AWS), Google Cloud Platform (GCP), and Microsoft Azure.
This release benefits from ecosystem-wide improvements including:
- Enhanced configuration and secret management, including cloud-native config import capabilities
- Updated cloud SDKs and dependencies
- Improved observability, metrics, logging, and tracing
- Continued support for serverless and container-based deployments
Whether deploying to OCI, AWS, Azure, GCP, Kubernetes, or other cloud environments, developers can take advantage of Micronaut’s lightweight runtime and GraalVM Native Image support to build efficient, production-ready services.
Extended Support for GDK 4.10
To provide additional flexibility for upgrades, we are extending support for the GDK 4.10-based release line through July 2027. This gives existing users more time to evaluate and adopt GDK 5 while continuing to receive updates on a stable, production-proven platform. For more information about GDK LTS releases and support, see the GDK support page.
