May your 2026 be as clean as your pom.xml:

🎊Wishing you a year where:

1. Your main() method stays simple and your classpath stays empty.
2. You forgot the import statements.
3. You never have to explain why you don't need Spring for a REST endpoint.
4. Your JAR files remain measured in kilobytes, not megabytes.

May your code compile faster than others can download their node_modules.

🥂 Here's to a year of:

jshell experiments

that actually make it to production

Records

that replace your boilerplate

Pattern matching

that makes your switch statements beautiful

Virtual threads

that make your concurrent code readable

String templates

that end your StringBuilder nightmares

May your dependencies be few, your JDK be current, and your NullPointerExceptions be... well, actually helpful now!

"🎆 In 2026, may you write code so clean that even the JVM garbage collector gets bored."

Happy New Year! May your builds be fast, your tests be green, and your stack traces be short!

The wishes were generated by zSmith, a Java 25 zero-dependency agent:

import airhacks.zsmith.agent.boundary.Agent;

void main() {
  var newYearAgent = new Agent(
  """
  As a marketing specialist,
  you focus on humorous wording
  for specific occasions,
  such as New Year's.
  """
  ).withTemperature(0.1f);

  var response = newYearAgent.chat("""
    Write New Year wishes for
    all the Java developers out
    there who write simple Java 25 code
    without any external dependencies.
  """);
  IO.println(response);
}

constructions.cloud provides a curated collection of Java-based AWS deployment examples using CDK infrastructure-as-code. The repository contains production-ready patterns for building serverless applications on AWS.

The collection includes repositories covering common AWS patterns:

Foundation & Setup

CDK development environment configuration and foundational templates

Serverless Compute

Lambda implementations from minimal POJO examples to Quarkus-powered HTTP APIs

AI Integration

Bedrock Agent Core implementations including runtime agents and MCP gateway patterns

Storage & CDN

S3 integration examples and CI/CD pipelines with CloudFront distribution

Each repository follows the bce.design architecture with minimal dependencies. The Quarkus examples replace traditional microservices with serverless HTTP APIs. The POJO examples handle AWS events (S3, SQS, EventBridge) without framework overhead.

Visit constructions.cloud to explore the collection.

Escape outdated JDK 1.X practices from the 90s with practical, modern Java development. This session provides concrete Java 21+ techniques that eliminate bloat, increase productivity, and streamline your business logic.

• Structuring efficient monoliths and microservices
• Streamlined testing approaches
• Logging and error handling
• Implement data-oriented programming
• Remoting and caching
• Persistence strategies
• Documentation and Javadoc
• Build and CI
• Replace external dependencies with built-in functionality
• Adapting code structure for LLM-driven development

I started with an empty project (Quarkus and MicroProfile), gradually adding features and tests and carrying out refactoring using the bce.design approach. I began with Claude Code, then moved on to Kiro.

There was a general agreement that beautiful Java code can be written really quickly. I hope I surprised some of the attendees! 😊

Some attendees handled 'TrainAboutToDepartException' with impressive speed, which is a positive sign.

A new Quarkus template is now available that provides an essential foundation for building MicroProfile applications using the Boundary-Control-Entity (BCE) architecture pattern. Available at github.com/AdamBien/quarkus-microprofile.

Key Features

BCE Architecture: The code is structured into distinct layers - boundaries (REST endpoints), control logic, and entities. This promotes maintainability while keeping the codebase minimalistic.

MicroProfile-Only: The template includes only JAX-RS for REST endpoints and CDI for dependency injection. No external dependencies.

Modular Structure:

• service: Core Quarkus application with BCE structure
• service-st: Separate system tests module

Technical Foundation

Built on Quarkus for fast startup and low memory footprint. The BCE pattern is the simplest way to organise your code, scaling to complex enterprise applications.

Getting Started

Clone the repository (github.com/AdamBien/quarkus-microprofile) and start building immediately. All necessary configuration files and basic project structure are included.

Arguably the oldest architecture pattern, BCE/ECB is described in countless articles and books, and is supported by most (all) design (drawing? 😊) tools.

Boundary Control Entity (BCE/ECB) is built on a simple structure that focuses on the business domain. A component is a (Java) package or module (e.g. ESM in Web Components) that focuses on a real business concept.
