Perhaps you’ve noticed some recent articles lately?
- Spring 5 moving up to Java 8+
- Massive adoption of Spring 4 and Java 8
- http://start.spring.io/ defaulting to Java 8 as the version of choice
- Spring Boot’s 1.3.0.M1 reference docs recommending new apps start at Java 8.
Okay, those last two aren’t articles, but were instead driven by the the rapid adoption of Java 8. Java 8 has been picked up by the development community FAST. Here on the Spring team, we believe strongly in adopting Java 8 for new applications. To support that and improve your own ability to move as well, we just updated all of the Spring Getting Started Guides to Java 8.
