Java 14 Reaches General Availability With Garbage Collection Improvements

Written by Michael Larabel in Oracle on 17 March 2020 at 05:06 PM EDT. 45 Comments

Java 14 has reached general availability today with numerous updates to the JDK.

Among the changes with Java 14 are:

- Records is available in a preview state. Records provide a compact syntax for declaring classes that are transparent holders for shallowly immutable data.

- The G1 garbage collector now supports NUMA-aware memory allocations.

- The ZGC (Z Garbage Collector) is an experimental feature on Windows and macOS.

- Improvements to Parallel GC.

- Thread suspend/resume has been deprecated.
