1. The unclear licensing model has been the most significant barrier to GraalVM adoption for years. However, at @JavaOne 2022, it was announced that @Oracle will make the GraalVM CE a part of the OpenJDK. Project Galahad has been set up to carry out the process - ❤️ that name. 
2. @Google announced that it was joining the @adoptium working group as a Strategic Member. Google didn't just limit itself to throwing piles of 💰 at JDK, but together with @AlibabaGroup began working on Java Class Pre-Initialization to accelerate the cold start of applications.
3. @JavaAtMicrosoft, however, decided to go even wider. The company became part of the standardization body for both @JakartaEE and @MicroProfile. @Azure is the first cloud to provide native application server support. @OracleWebLogic and @jbossorg EAP are available right now.
4. To sum up the Cloud Providers topic, @Payara_Fish announced Payara Cloud. The way it works is that you take your Jakarta-compliant *.war, upload it to the cloud, and... you're done. Their "forget about my cloud-native application" approach seems all too tempting.
5. @Android 13 brought support for #OpenJDK 11, e.g. the ability to use var, VarHandle with java.util.concurrent, or many other additional APIs. It's apparent that the results of the 2021 Google/Oracle 👨⚖️ have untied the Android's developers' hands.
6. #ProjectLoom hasn't really been off the tongues in 2022, but the most exciting was the announcement of #Helidon Níma by @helidon_project. It turns out that we are getting ready for the first framework in which Loom will not be a tacked-on add-on, but a "First-Class Citizen."
7. Starting with version 2.7, #Akka changed its licensing model from Apache 2.0 to BSL v1.1. That marks the closure of Akka's development phase based on the so-called "Open Core." The new versions will continue to be released under Apache 2.0, but with a delay - three years one.
8. Shall we remember 2022 as the year when the Java "cold start" problem was finally solved, at least on #AWS? @awscloud showed AWS Lambda #SnapStart. It saves the Lambda's memory state at the initialization and puts it "aside" for later use when our function is not hot anymore.
9. @JakartaEE 10 was released. The single biggest changes in the new release are CDI Lite and a new Profile - Core, in addition to Full and Web ones. It standardized a set of APIs used in the Microservice context and was already adopted by @MicroProfileIO in its 6.0 version.
10. In an era of a regular "release train," @WildFlyAS took a step back and decide to base releases on defined sets of functionality. This is a return to the roots when new releases of application servers were much less frequent and associated with big bumps in the standards.
11. #MachineLearning has made its way into the Java standard through the JSR-381 Visual Recognition (VisRec) Specification. Contrary to the misleading name, this is a high-level API standard for basic machine learning (ML) as well as image classification and object recognition.
12. @bellsoftware - the developers of the #LibericaJDK - decided to create a new reference Linux distribution designed directly to run Java in containers named Alpaquita Linux. The developers have taken minimalist @alpinelinux but modified it to better support Java needs.
13. @java 18 and @java 19 were released. They brought Simple Web Server, Code Snippets in Java Docs, support for RISC-V CPUs, but also preview versions of #ProjectLoom (VirtualThreads ❤️), #ProjectPanama, and many of the #ProjectAmber APIs like pattern matching.
14. @kotlin 1.7 released the alpha version of the K2 compiler. The alpha version supports only the JVM for now and is still quite limited, but the first test release is a very important step for the whole project.
15. #Groovy 4.0 has been released and had mostly java-compatibility features. The most of more interesting parts like GINQ - Groovy-Integrated Query or Groovy Contracts are still in incubation. However, in 2022, most people probably use Groovy as a runner for @spockframework.
16. #Clojure 1.11, the first new version since 2018, provides a new syntax - functions that accept keyword arguments can now receive a map instead of key/value pairs. It also brings a new namespace clojure.math, wrapping the methods available in java.lang.Math
17. The end of 2022 saw the release of @springframework 6.0 and @SpringBoot 3.0, requiring JDK 17. It got rid of the javax.* package in favor of jakarta.* and focuses particularly on Ahead-of-Time compilation support, to modernize the project on par with the recent competition.
18. @Hibernate 6.0 is an edition that is the first Hibernate "major" since 2011. It is all about new annotations, which abandoned their XML roots and received a lot of changes e.g. better type safety. A very big change is also the migration of Hibernate to Jakarta EE 9.1+.
19. #AWS SDK for #Kotlin with Coroutine support was released It's nice of AWS to opt for a special Kotlin edition - while the compatibility of this language with Java is sufficient, it's good that after 2022 we won't have to resort to it too often.
20. @vaadin 23 drops support for Java older than 11, and introduces changes to Vaadin's design system. It also brought two new sub-frameworks: Flow, which is used to generate JavaScript code 100% from within Java and Hille, which combines the @SpringBoot backend with @typescript
If you are still here - thank you for your perseverance 🎉. And I hope 2023 will be as interesting as 2022 🤩
