Java Virtual Machine Tools Interface
（重定向自JVMTI）
Java Virtual Machine Tool Interface (JVMTI, or more properly, JVM TI) was introduced in J2SE 5.0 (Tiger). This interface allows a program to inspect the state and to control the execution of applications running in the Java Virtual Machine (JVM). JVMTI is designed to provide an Application Programming Interface (API) for the development of tools that need access to the state of the JVM. Examples for such tools are debuggers or profilers.
