2026.09.07 → [JAVA 17 RUNS OUT OF PREMIER SUPPORT THIS MONTH](https://www.paul-piper.de/posts/java-lts-cadence-enterprise-consulting/)

Java 17’s Premier Support runs out on 30 September 2026, according to endoflife.date, and in fifteen years of walking into large Java codebases I have never once seen a date like that be the actual reason a company moved. I spent that time as an enterprise Java consultant, in places like a bank’s core ledger, an airline’s distribution system, a public administration’s case management platform. Every one of them had a support calendar pinned to a wall or a wiki page somewhere.
