未来，JRockit与HotSpot将会合并为单独一个JVM，互相取长补短。合并后的成果将会持续不断地加到OpenJDK当中。Oracle将会继续维护开源与闭源的JDK实现。Sun的Java for Business与Oracle的JRockit Mission Control、JRockit Real Time以及JRockit Virtual Edition仍将受专利保护并使用商业协议，他们是付费产品。详见[http://docs.huihoo.com/java/JVM-Strategy-2010.pdf JVM的未来策略]

在 Java 8 中，与云相关的最重要的两个特性就是多租户与模块化：
 +
*多租户：指的是在一个 Java 虚拟机（JVM）中安全运行多个应用的能力。
 +
*模块化：指的是把 JDK 重新组织为一套尽管互相依赖但却是定义清晰的模块。Java 开发人员的一个替代选择是使用 [[OSGi]]。

目录

[编辑] 简介

Today this project contains two significant components of the JDK:

  • The HotSpot Virtual Machine
  • The Java programming-language compiler (javac)

目前，OpenJDK 采取 GPL 2 许可协议

未来，JRockit与HotSpot将会合并为单独一个JVM，互相取长补短。合并后的成果将会持续不断地加到OpenJDK当中。Oracle将会继续维护开源与闭源的JDK实现。Sun的Java for Business与Oracle的JRockit Mission Control、JRockit Real Time以及JRockit Virtual Edition仍将受专利保护并使用商业协议，他们是付费产品。详见JVM的未来策略
