Life Beyond Java 8

New versions of Java are coming out every six months. What has changed, should we upgrade, and if so, how?

Abstract

Wasn’t Java 8 a fantastic update to the language? Lambdas and streams were a huge change and have helped to improve Java developers’ productivity and introduce some functional ideas to the language. Then came Java 9… and although the module system is really interesting for certain types of applications, the lack of exciting language features and uncertainty around how painful it might be to migrate to Java 9 left many applications taking a wait-and-see approach, happy with Java 8.

But now, Java has a new version every six months, and suddenly, Java 12 is here. But we’re all still on Java 8, wondering whether we should move to a later version, which one to choose, and how painful it might be to upgrade.

In this session, we’ll look at:

  • Why upgrade from Java 8, including language features from Java 9, 10, 11, and 12
  • What sorts of issues might we run into if we do choose to upgrade
  • How the support and license changes that came in with Java 11 might impact us.
