JEP 388: Windows/AArch64 Port introduces the official support for running Java on Windows systems with AArch64 (ARM 64-bit) architecture in Java 17. Prior to this enhancement, Windows support for ARM architecture was limited and often required workarounds or was not as fully supported as on x64 (Intel/AMD) systems. This improvement brings AArch64 support on Windows …
JEP 376: ZGC on Windows is an enhancement introduced in Java 17 that extends the support for Z Garbage Collector (ZGC) to the Windows platform. Prior to this enhancement, ZGC was available only on Linux and macOS. This update allows Java applications running on Windows to take advantage of the low-latency, scalable features of ZGC, …
Concurrent collections are specialized data structures in programming that facilitate safe and efficient manipulation of shared data by multiple threads in a concurrent environment. Traditional collections, like lists, queues, or maps, often face issues like race conditions when accessed by multiple threads simultaneously. Concurrent collections address these issues by providing built-in thread-safe operations. Concurrent collections …
JEP 400 introduces UTF-8 as the default character encoding in Java 17. Previously, the default encoding depended on the operating system’s locale, which caused inconsistencies across different platforms. This enhancement ensures that Java applications behave consistently and reliably, especially when handling text data in various languages. Key Changes UTF-8 as Default: UTF-8 is now the …
JEP 338: Unix-Domain Socket Channels was introduced in Java 17 to provide enhanced support for Unix-domain sockets (UDS) in the Java platform. This improvement enables developers to utilize the power and efficiency of Unix-domain sockets for inter-process communication (IPC) on Unix-based systems. Unix-domain sockets are a powerful communication mechanism that allows processes on the same …
JEP 376: ZGC on macOS introduces the support for the Z Garbage Collector (ZGC) on macOS in Java 17, marking a significant milestone in the evolution of the ZGC as a low-latency garbage collector. Prior to this enhancement, ZGC was available on Linux platforms but not on macOS, limiting its use for macOS users. With …
JEP 336: Deprecate the Security Manager for Removal introduces the deprecation of the Security Manager in Java 17, signaling its eventual removal in future versions of the JDK. The Security Manager was originally designed to enforce fine-grained security policies and restrict access to sensitive resources, but over time, its usage has significantly declined. This JEP …

JEP 392: Packaging Tool is a significant enhancement introduced in Java 17 that provides a simpler, more streamlined way to package Java applications into platform-specific executables. This tool aims to ease the process of deploying Java applications by allowing developers to package their applications with native installers or executables, thereby eliminating the need for users …
JEP 387 (Elastic Metaspace) was introduced in Java 17 to enhance the management of Metaspace, particularly in reducing the overall memory footprint for applications. Metaspace is an area of memory where class metadata is stored in Java. Unlike the Permanent Generation (used in older Java versions), Metaspace was introduced in Java 8 and stored class …
The Vector API introduced as part of JEP 338 aims to provide a platform-independent API to express vector operations in Java. It was first incubated in Java 16 and enhanced in subsequent releases. This API allows developers to write high-performance vectorized code that can take advantage of SIMD (Single Instruction, Multiple Data) capabilities provided by …
