JAZ, Copilot SDK, and Why LLMs Write Better Java

An airhacks.fm conversation with Bruno Borges (@brunoborges) about: discussion about the JAZ command launcher for Java, JVM tuning and default ergonomics for containers versus dedicated cloud environments, replacing the Java launcher with jaz in container images, supporting Java 8 to 25, maximizing resource utilization on kubernetes to reduce waste, running Java on Azure Functions, Azure App Service deploying a fat JAR without a container image, Azure Container Apps as a platform on AKS without YAML, Azure Kubernetes Service and AKS Automatic, Bicep as infrastructure as code, deploying a JAR to Kubernetes via OCI artifacts and a custom operator, Microsoft Foundry and the Microsoft Agent Framework, Semantic Kernel learnings, the Copilot SDK for Java communicating with headless CLIs, A2A and ACP protocols and MCP, agents as microservices with scoped tasks, guardrails, and sandboxing, per-agent model selection for cost and reasoning trade-offs, observability and traceability between agents with opentelemetry, grounding LLMs against MicroProfile, Jakarta EE, JAX-RS normative RFC 2119 specifications for hallucination-free Java code generation, the Boundary Control Entity pattern and business components as Java packages, package-info.java for semantic context, GitHub Copilot skills and custom instructions in Visual Studio Code, the AI Rails skills site, zero-dependency Java CLI scripting, reducing dependencies by reusing source code instead of JARs, the org.json reference implementation reduced to five classes, StackGres and OnGres running Quarkus and GraalVM to manage Postgres on Kubernetes, the Digg Into Java community
