8 Hacker News commenters recommended JDK and 13 criticized it, November 2025 to November 2026. It was recommended in 2 of 13 months.

**Verdict:** Developers recommend the JDK for its low runtime overhead and compact footprint improving with each release since Java 17. Critics warn that Oracle's distribution carries licensing and enforcement risk.

- Oracle licensing and enforcement risk (5 comments): "I don't understand why anyone would actively choose to use a JVM from Oracle if they can avoid it." ([source](https://news.ycombinator.com/item?id=47589920)) "They still love to play the old Oracle tricks, so I'd rather not use any of their distributions." ([source](https://news.ycombinator.com/item?id=47425321)) "Their licensing can get expensive and they are famously pretty aggressive on enforcing terms."

- Slow cold start and warmup (3 comments): "We are moving away from it in our serverless functions due to the cold start times." ([source](https://news.ycombinator.com/item?id=50137364)) "Almost all Java benchmarks are for the "steady state" after half an hour of warm up time."
