Articles on Java, Spring Boot, Kubernetes, Docker and AI engineering: agents, LLMs, MCP, RAG and prompt-injection defence. Most are on Medium and link out. Newest first.

14 Oct Notes on this site What this site is for, how the cluster at the top works, and where the writing lives.
8 Sept WebMCP: Give AI Agents Real Tools on Your Website What WebMCP is, how it differs from MCP, the API, and what to watch for when you add it to a site. Level Up Coding
5 Sept Prompt Injection Defense for Java Devs (Part 2): RAG, Egress, and What Comes Next Layers four to six of the defence, for retrieved RAG content and data egress, and where Dual-LLM, CaMeL and Llama Guard fit. Javarevisited
30 Jul Value Objects in Java 28: Integer Finally Behaves Like int JEP 401 lets classes opt out of identity, so == compares values and the JVM can flatten your objects like primitives. Javarevisited
2 Jun Prompt Injection Defense for Java Devs (Part 1): Locking Down Inputs, Outputs, and Tools The threat model and the first three layers of defence for a Spring Boot LLM app: input boundaries, output validation and tool-use guardrails. Javarevisited
5 May Spring AI + pgvector: A Beginner’s Guide to RAG Build your first Retrieval-Augmented Generation app in Spring Boot with Docker, OpenAI, and a vector database that lives inside Postgres. Javarevisited
4 May Why Coding Agents Love Git Worktrees One repo, many working directories, and how AI coding agents use them to run tasks in parallel without stepping on each other. Level Up Coding
3 May Building an MCP Server in Spring Boot: The Definitive Java Guide MCP is becoming the USB-C of AI tooling, but most tutorials are in Python or TypeScript. This is the production-ready Java guide, with LLM integration. Javarevisited
10 Apr Why Most AI Agents Fail in Production Hallucinations, black-box pipelines and missing guardrails, and how to build agents that still work on day two. AI Advances
8 Apr Write Java, Run on GPUs: How Project Babylon Changes Everything Project Babylon lets Java code run on GPUs without CUDA or OpenCL, extending Write Once, Run Anywhere to AI workloads. Javarevisited
4 Apr Why Your Spring Data Queries Break After Every Refactor Spring Data introduces type-safe property paths, replacing fragile string references with method references the compiler understands. Javarevisited
16 Mar Java Streams Were Missing One Thing. Java 22 Finally Fixed It. Collectors always forced your stream to stop. Gatherers in Java 22 let it keep going, with state, windows and full control. Javarevisited
16 Mar Your Coding Instincts Are Broken. AI Agents Just Exposed That. Everything you know about software trade-offs was calibrated for a world where writing code was expensive. That world is gone. Level Up Coding
21 Feb Java Already Ships a Logger. Almost Nobody Uses It. System.Logger, the quiet API added in Java 9, removes a whole class of logging dependencies. Javarevisited
21 Feb Your Retry Logic Is Probably Broken. Spring Boot 4 Just Fixed That For You Spring Boot 4 ships native retry in org.springframework.resilience, and the API has nuances most articles get wrong. Javarevisited
17 Jan Java Runs Out of Memory, Yet This Code Still Executes How the JVM plans for memory failure long before your heap fills, and why code still runs after an OutOfMemoryError. Javarevisited
1 Jan AI Writes Code Faster. Humans Still Ship Better Software An analysis of hundreds of GitHub pull requests shows AI-generated code has more bugs in logic, security and performance. Level Up Coding
