Preface
This guide helps users of Oracle JRockit to migrate to Java HotSpot VM (Java Platform, Standard Edition). The document describes the command-line options and tools available in Oracle JRockit, and their equivalents in the Java HotSpot VM (HotSpot).
Audience
The target audiences for this document are developers and users who are working on Oracle JRockit and planning to migrate to the Java Development Kit (JDK). The JDK is Oracle's implementation of the Java Platform, Standard Edition (Java SE). The current release is Java SE 11 and JDK 11. However, most of the information in this document can be applied to releases earlier than JDK 11.
This document is intended for readers who have a detailed understanding of the Java HotSpot VM components, and also have some understanding of concepts such as garbage collection, threads, and native libraries. In addition, it is assumed that the reader is reasonably proficient with the operating systems where the Java application is developed and run.
