OrlandoJUG Reading List ::: from JavaSpecialists
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.Issue 297 - Measuring ForkJoinPool Parallelism
Java has support for parallelism baked into the JDK. We have parallel streams, parallel sort and CompletableFutures, all using the same common ForkJoinPool. In this newsletter we explore how to measure the effectiveness of our parallelism.Issue 296 - Concurrent LinkedHashSet
LinkedHashSet is a set that can also maintain order. To make this thread-safe, we can wrap it with Collections.synchronizedSet(). However, this is not a good option, because iteration would still be fast-fail. And what's the point of a thread-safe LinkedHashSet that we cannot iterate over? In this newsletter we try to create a concurrent set that behaves like a LinkedHashSet, but with minimal locking and with a weakly-consistent iteration.Comment Wall

InfoQ Reading List
Article: The What and Why of Programmable Proxies
A question which gets often asked is “What is a programmable proxy, and why do I need one?” This article tries to answer this question from different perspectives. We will start with a brief definition of what a proxy is, then discuss how proxies evolved, explaining what needs they responded to and what benefits they offered at each stage. Finally, we discuss several aspects of programmability.

By Andrea MessettiMicrosoft + Java = ♡: a Story Told by Martijn Verburg at Devoxx UK
Three years after Microsoft acquired jClarity, Martjin Verburg presented at Devoxx UK on how reliant Microsoft is on Java. If the two didn’t seem to fit on the same page, the reality is different: Microsoft runs 2 M JVMs in production for internal purposes, 50+ Android apps, and Azure’s internal systems and Minecraft are built in Java. Moreover, Microsoft is committed to moving Java forward.

By Cassie BreviuTrust-Driven Development: Building Cognitive and Emotional Pillars
Trust-driven development uses authenticity to build a safe environment for people to operate. To build trust we need to focus on two main pillars of trust – cognitive and emotional. We need to be brave, have courage, and give people access to our authentic selves.
