Java news Roundup: Spring 6.0 and Spring Boot 3.0, OpenJDK and Quarkus update roadmap

This week’s Java Roundup for August 30, 2021 contains news from SpringOne, It reveals the roadmap for Spring Framework 6.0 and Spring Boot 3.0, OpenJDK JEP updates, JDK 18, Quarkus 2.1 and 2.2 release series updates, and MicroProfile APIS Release candidate, Open Liberty 21.0.0.9, Hibernate 5.6.0.Beta1, GraalVM Native Build Tools 0.9.4, and Helidon’s new JHipster project.

OpenJDK

JEP 400, UTF-8 by Default has been upgraded from Proposed to Target in JDK 18 to Integrated status. The JEP specifies that UTF-8 is the default character set for the standard Java API to ensure all implementations, operating systems, locales, and configurations.

A week after being promoted to Proposed Target status, JEP 413, Code Snippets in Java API Documentation, has been promoted to Targeted state in JDK 18. The JEP introduces the tags of **@snippet**Oracle standard Doclet, which is the well-known Java API document utility that generates default HTML output. The goal is to simplify the process of including the sample source code in the API documentation.

JEP 418, the Internet Address Resolution SPI, has been upgraded from draft to candidate status. The JEP recommends defining a service provider interface for hostname and address resolution so that **java.net.InetAddress** can leverage parsers other than the default built-in OpenJDK parser.

Geertjan Wielenga, senior director of open source projects at Azul, has been kicking off the “Engineering with OpenJDK” campaign, which builds on top of OpenJDK highlights. Java developers are encouraged to add badges, as shown below. For example, you can add ** readme.md ** to a file in your application’s GitHub repository.

For Maven users, this will be necessary to use the configuration generation. maven-shade-plugin
