| gptkbp:description |
Introduces a new rendering pipeline for mac OS.
This JEP proposes to enhance the existing pseudo-random number generators in the java.util.random package. Introduces sealed classes and interfaces to restrict which classes can extend or implement them. Provides a mechanism for streaming Java Flight Recorder events. Enhances Z Garbage Collector to support concurrent class unloading. |
