#JavaTuesdayThread
I’ve been patiently waiting for JEP 429 publishing with my fingers crossed for quite a while since JEP 425 appeared in a public space (although my story with Project Loom is longer than you can imagine). So, today’s topic is - extent-local variables. #Java

When we started talking about virtual threads the question we've been asked is whether virtual threads are like the old ones. The answer was YES, however, some techniques used to organize the data flow around platform threads may not be valid (but working) for virtual threads.
By saying “some” we’re mostly pointing to thread locals. As you you know, it’s possible to start over 10M threads for nothing while it’s not the same for platform threads because the JVM, like the other processes, has a thread count limitation it cannot surpass.

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.
