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.

Today I’d like to speak a bit regarding #Java Flight Recorder (JFR) and how far you can get with it. #OpenJDK #JFR #JMC

So, as you may know, a few releases ago, Java developers were able to create, publish, and react to particular JDK events, also known as JFR.
The first and most important JFR feature is that the whole JDK is pierced with tons of JFR events. You can enable them to get most of the information about what’s going on with the JVM.
It's time for #JavaTuesdayThread!
You know that JDK 19 will be released in 2 months on Sept. 20th. It will bring some major changes to the JDK. Project #Loom is one of those HUGE changes I want to talk about a little bit more. #Java #OpenJDK

JEP 425 introduces Virtual Threads. The most interesting thing is that the JDK was reworked to make it possible to block both platform and virtual threads in different ways.
While thread blocking methods will put on pause the whole platform thread, the virtual thread blocking wouldn't block its underlying carrier thread so it can pick up the segment of another virtual thread to execute.
#Java has been and continues to be the most popular language over the last two decades. After many discussions with Java developers, I have concluded the following seven key reasons why Java developers still love Java after all these years.
1. Community:
In every major city, you will find a Java user group that helps developers achieve the required skills, voluntarily and for free, who help distribute resources and solutions, increase networking, and expand #Java knowledge globally. dev.java/community/jugs/.

2. Language and Platform
An expressive and easy-to-read language helps new developers quickly get used to the existing codebase. #Java is an open-source programming platform with great documentation support. It's a platform that houses and enables a wide range of other languages.

TIL #Log4j depends on some Java SE modules that IMO shouldn't.
- java.desktop
- java.management
IMO, all logging frameworks (core functionalities) should depend only on java.base and java.logging.
Anything else should be a separate extension/artifact.

While 'java.naming' is also a dependency, #Log4j works fine without it.
It won't operate at all if java.desktop and java.management are missing.
Removing 'java.naming' module from a jlinked runtime is the ultimate protection against JNDI attacks in Java.

Of course, all this is understandable given these are logging frameworks that predate Java 9.
But as we think forward and evaluate new major versions and libraries, we should be mindful of using only what we need.

⏱️ Just ten more days until the release of @java 17, the next version with long-term support! To shorten the waiting time a bit, I'll do one tweet per day on a cool feature added since 11 (previous LTS), introducing just some of the changes making worth the upgrade. Let's go 🚀!
🔟 Ambigous null pointer exceptions were a true annoyance in the past. Not a problem any longer since Java 14: Helpful NPEs (JEP 358, openjdk.java.net/jeps/358) now exactly show which variable is null. A very nice improvement to #OpenJDK, previously available only in SAP's JVM.
9⃣ Varying load and new app instances must be started up quickly? Check out class-data sharing (CDS), whose dev exp has improved a lot with JEP 350 (Dynamic CDS Archives, Java 13); also way more classes are archiveable since Java 15. More details here: morling.dev/blog/smaller-f…
Essa é uma thread sobre as novidades do #MSBuild. Cada tuite terá uma das novidades que achei mais interessantes pra devs. Vem junto, tem muita coisa legal!
Azure Application Services (App SErvice, Functions, Logic Apps, Event Grid e API Management) agora rodam no Kubernetes (em preview), em qualquer lugar onde você tenha k8s, até em outras clouds. Incrível!

The inaugural @OracleCodeOne conference is over.
Now’s the oppty to watch recorded sessions by members of the @Java Platform Team @Oracle. Learn how #Oracle is continuing to keep #Java vibrant.
Without further ado, here’s my replay suggestions (re-tweets welcomed)...
