It's a JEP!

JEP 378 – Text blocks leave preview in JDK 15

Text blocks were added to Java as a preview feature in JDK 13. With JDK 14 the feature was previewed for a second time with the addition of two more escape clauses. Now, text blocks will be a full-fledged feature in JDK 15 because the community is in agreement: text blocks are ready. Let’s take a closer look.

Quarkus – an IO thread and a worker thread walk into a bar: a microbenchmark story

A competitor recently published a microbenchmark comparing the performance of their stack to Quarkus. The Quarkus team feels this microbenchmark shouldn’t be taken at face value because it wasn’t making a like-to-like comparison leading to incorrect conclusions. Both of the two frameworks under comparison support reactive processing. Reactive processing enables running the business logic directly on the IO thread, which ultimately performs better in microbenchmark focusing on response time and concurrency. The microbenchmark should have been written so that both frameworks (or neither framework) obtain this benefit. Anyway, this turns out to be a very interesting topic and good information for Quarkus users, so read on.

Improved startup with syntax server

Slow startup and large footprint will be a thing of the past

Project Leyden to bring static images to the Java platform and JDK

Chief Architect of the Java Platform Group at Oracle, Mark Reinhold, has written a call for discussion proposing a new project, Project Leyden, that will address the long-term pain points of Java’s slow startup time, slow time to peak performance, and large footprint. It will do this by introducing static images to the Java platform and JDK. Let’s take a closer look.

JEP 376: ZGC – Concurrent Thread-Stack Processing

Almost there – Garbage collection with the Z Garbage Collector is almost completely free of infamous safepoint operations. Stack processing is the only thing not really running in a concurrent phase yet. JEP 376 addresses exactly this problem and should finally put an end to unnecessary pauses. Let’s take a closer look.
