What’s This?

This is the Java Full-Stack Report for April 2022. It has technology recommendations, important releases, and news. My technology recommendations are partially based on measured popularity. This month: Spring Boot’s zero-day exploit gets worse, New Relic’s “State of Java” report, React and React Native surge in job ad mentions, and my InfoQ article series on native Java started to show.

This issue is late because I gave a talk at QCon London and updated all job charts, I spoke at JavaLand in Germany and the Google Developer Group Milton Keynes.

Technology Index

Popularity trends: Kotlin, Postgres, Jakarta EE, and Flutter are the “losers of job ad mentions” this month. Quarkus is #3 in job ads mentions for the first time (behind Spring Boot & Jakarta EE). Also, see my recommendations for a JVM language, a database, a back-end framework, a web framework, and a mobile app framework.

Release Radar

OpenJDK, Micronaut, Eclipse, VS Code, and Netbeans had major releases. Maven, Gradle, Spring Boot, Quarkus, and DropWizard had minor ones.

New & Noteworthy

Java 18 is here, zero-day exploit hits Spring Boot, and Java Heap Deep Dive, Part 2.
