Jikes研究虚拟机（Jikes Research Virtual Machine,简称Jikes RVM)是一种成熟的用于执行Java程序的虚拟机，其早期版本与当前版本分别在通用公共许可证（CPL）与Eclipse公共许可证（EPL）下开放代码。与其他以Java编写的虚拟机不同的是，Jikes RVM采用了元循环技术。



Jikes RVM采用了元循环技术，因而其需要运行在一个引导Java虚拟机（JVM）上来创建启动镜像。启动镜像在运行时由一个小型的C装入程序载入，其本质是Jikes RVM启动必须的对象的集合，这些对象则是利用引导JVM的反馈所创建。



编译器在VM Magic里为一个类生成不同的代码（而非字节码）。VM Magic类允许对内存的直接访问，是影响内存管理工具包的性能的关键所在。VM Magic类被包含于org.vmmagic包内，同时也为其他的Java项目所使用。-Jikes Research Virtual Machine (Jikes Research Virtual Machine, referred Jikes RVM) is a mature virtual machine for executing Java program, its earlier versions and the current version of the General Public License (CPL) and the Eclipse Public License (EPL code) under the open. Written in Java virtual machine, Jikes RVM uses meta-cycle technology. The Jikes RVM adopt meta-cycle technology, and thus the need to run in a guide Java Virtual Machine (JVM) up to create a boot image. Start the mirror loaded at run-time by a small C-loader, by its very nature is a the Jikes RVM start must be the object of a collection of these objects feedback is used to guide the JVM created. Generated by the compiler as a class in the VM Magic different code (rather than byte code). VM Magic class allows direct access to the memory, the key to affect the performance of the memory management toolkit. VM Magic class is included in the the org.vmmagic package, also be used for other Java projects.
