What’s New?

JDK 17 is the first LTS release since JDK 11 and provides a range of both new Java language features and class libraries. Probably the most significant language change is the introduction of records, which eliminates almost all the boiler-plate code previously required for simple data classes. Looking at the libraries, the Foreign Memory and Foreign Function APIs are a much simpler way of using libraries developed in different languages than the old JNI approach.


Only the JDK 17 version of this Feature Preview is available. Follow the Quick Start Guide for your operating system, but replace the main Stream Release repository URL listed in those guides with the Feature Preview repository URL as listed below:

  • RHEL

    sudo curl -o /etc/yum.repos.d/zing.repo
