A practical guide to thread-safe native memory access in Java using VarHandle access modes, covering Plain, Opaque, Acquire/Release, and Volatile with JCStress tests to prove each guarantee.
A practical guide to managing native memory in Java using the Foreign Function & Memory API, covering Arenas, manual allocation, pooling, and slicing
In this post, we dive into how to perform pointer arithmetic using the Foreign Function & Memory API to achieve zero-GC memory access.
The first part where we introduce project Panama and show some of the basics. We will keep building on this knowledge in the other parts.
A simple helper class that makes Foreign Function Interface calls much nicer to work with. In this post we explore how this utility class works and how to use it effectively with records.
In this post, we take a look at how to benchmark Java code
In this post we cover how to use the memory segments introduced in Java 22
In this post we cover how to throw, catch, and handle different kind of built in and self made exceptions
When I first started exploring Virtual Threads in Java, I wanted to understand everything about them like, performance characteristics, when they yield, and limitations. This journey led me to an interesting challenge about file I/O operations. These operations cause Virtual Threads to become “pinned” to platform threads, limiting their effectiveness for I/O-heavy applications. This…
In this post, we look at how to do Java development for Linux while working on Mac OS.
