A couple of weeks ago, someone asked: "Why use GenAI when we know it hallucinates?"

My answer was: it depends.

Last week, my team discussed downgrading a library because our production service couldn't upgrade to JDK 21 due to Scala ecosystem limitations.

I got curious: could we upgrade to JDK 21 instead?

Thirty minutes with an AI agent later, the build passed. A couple hours of debugging and team collaboration later, we had a validated upgrade - an experiment I wouldn't have tried two years ago, and one that would've rotted on our backlog in the traditional model.

#java #scala #llm
