Issue 302 - Virtual Thread Deadlocks
Virtual threads can deadlock, just like platform threads. Depending on what state they are in, this might be quite challenging to analyze. In this newsletter we explore some tricks on how to find and solve them.Issue 301 - Gazillion Virtual Threads
As from this month, Project Loom is part of the mainstream OpenJDK as a preview feature. Expect fantastical results, as bloggers around the world kick the tyres of this fantastic technology. In this newsletter we show how we can have over 36 billion parked virtual threads in just 4 gigabytes of memory!Issue 300 - Break in Switch With Pattern Matching
The enhanced switch is cool. Pattern Matching for switch is super cool (they even timed the JEP number to be exactly 420 - or was that fate?). But what happens when we use "break" inside the case statement? Let's find out.Issue 299 - Synchronizing on Value-Based Classes
Locking on Integer objects has always been a bad idea. And we now have a way to find such bad code with a runtime switch DiagnoseSyncOnValueBasedClasses.Issue 298 - Finding Permitted Subclasses
Sealed classes show us which subclasses they permitted. Unfortunately there is no way to do this recursively. In this newsletter we show how to navigate the sealed class hierarchy and write a ClassSpliterator that can then create a Stream of classes.Birthdays
