![]() ![]() If you require to use an older version, Micronaut framework 3.x continues to support Java 8, Java 11, and Java 17. How to continue using Java 8 or 11 with the Micronaut Framework? Your code will run faster and your coding experience will be more productive. It is time for the Java community to update to 17. We, as framework developers, should put a stake in the sand. The Java community should embrace a least Java 17. Thus, we can deliver features faster to the Micronaut community. New Features, Changes, and Notable Bug Fixes For information about the new features, changes, and notable bug fixes included in the JDK 16.0.2, 11.0.12 (Long Term Support), 8u301, and 7u311 update releases, see the following release notes: JDK 16.0.2 Release Notes JDK 11.0. We can build and test our modules faster by dropping support for old Java versions in Micronaut framework 4.0. JDK 16 Release Java 16 / JDK 16 has now been officially released, below are proposed features coming out as part of the jdk 16. ![]() Our Java 17 builds are way faster – up to 30%. Micronaut framework 3.0 continuous integration tests run with a matrix of Java versions – 8, 11, and 17. By building and releasing artifacts with a baseline of Java 17, Micronaut users will get performance benefits when updating their applications to the latest Framework version. The Java 16 release is the result of industry-wide development involving open review, weekly builds and extensive collaboration between Oracle engineers and members of the worldwide Java developer community via the OpenJDK Community and the Java Community Process. Java 17 is significantly faster than Java 8 or 11. By setting a Java 17 baseline, we can update those code samples to use Java’s newest features which make Java a much more appealing language and development experience. Micronaut Guides and Micronaut modules documentation embed code samples from real code. ![]() For example, Azure Functions, AWS Elastic Beanstalk, Google Cloud Functions or OCI (Oracle Cloud Infrastructure) Functions support Java 17 runtimes. Many Micronaut users deploy to the cloud. Moreover, we can improve our internal code and public APIs using features such as Java Records, Sealed Classes, Switch Expressions, Text Blocks, and Pattern matching for instanceof. There are a couple of good changes on NIO and new File API, and lots of other at the API level, which is also worth looking at. For example, Micronaut framework 4.0 provides an alternative implementation of the Micronaut HTTP Client based on Java HTTP Client. Use modern Java featuresīy setting a Java 17 baseline, we can use new Java features. Starting with Micronaut framework 4.0, to be released in 2023, the Java baseline will be Java 17.
