We are very excited to announce our new open source, cloud agnostic, serverless platform–Fn #JavaOne

The latest Inside Java Newscast tells the story of the structure and community that fixes OpenJDK bugs and how they operate. 🐜 You'll also get look at #JavaOne, the Inside Java Podcast, and JDK 28.

One example was a larger end-to-end support system built from several cooperating Java services: a patient fills in a complaint via a web application, that request becomes a helpdesk ticket, and an AI-based triage pipeline speeds up its solution. The Model Context Protocol server for urgency scoring only appeared briefly in the presentation, so this article covers the design decisions behind that MCP server and its possible role in the triage workflow: Given a complaint message, how urgent is it?
