Trade OMS Java Core - Institutional Microservices Foundation

Release Notes: v1.0.0-alpha
Project: Trade Order Management System (OMS) | Java Enterprise Layer

Organization: Castle Trade LLC - Infrastructure Division

Date: April 2026

Executive Summary
This release establishes the enterprise-grade foundation for the Castle Trade Order Management System (OMS). Built with Java 21 and Spring Boot 3, this core module is engineered for high-throughput and low-latency order processing, utilizing the latest advancements in Java's concurrency model (Virtual Threads) and reactive programming.

Architectural Highlights
Reactive Order Processing: Implementation of non-blocking I/O via Spring WebFlux and Project Reactor to handle thousands of concurrent order submissions with minimal resource overhead.

Virtual Threads Integration: Optimized for Java 21 Loom, ensuring that the system can scale horizontally in cloud-native environments without the traditional thread-per-request bottlenecks.

Clean Architecture (Hexagonal): Strict separation between domain logic and infrastructure ports/adapters, allowing for seamless integration with different database engines (R2DBC) or execution venues.

Dockerized Deployment: Multi-stage Dockerfile included for production-ready containerization, reducing the attack surface and optimizing image size for AWS/Kubernetes.

Technical Stack
Language: Java 21 (LTS)

Framework: Spring Boot 3.x

Paradigm: Reactive Microservices / Event-Driven Ready

Build Tool: Maven
