According to a new study, nearly two-thirds of Java developers have already migrated to Java 8, or are committed to doing so within the next year. The survey, conducted in September 2014 by Typesafe, which helps developers build applications on Java Virtual Machine (JVM), indicates that developers are upgrading ahead of the predictions made in Typesafe's March survey. While Java 8 adopters are aggressively embracing the new release, holdouts cite legacy architectures, not Java 8 features, as the biggest obstacle to upgrading, according to the survey. "It's truly remarkable how quickly the Java developer community has rallied around Java 8," says Jonas Bonér, CTO and co-founder of Typesafe. "Innovation around Java and the JVM is transforming the modern data center infrastructure." The survey polled 3,030 coders, 61 percent of whom identified themselves as developers, while 27 percent checked off architect. Twenty-six percent code full time, and 55 percent spend more than half their workday coding.
