Java Virtual Machine Tool Interface (JVMTI)

JVMTI is a new native programming interface for use by development and monitoring tools. It provides both a way to inspect the state and to control the execution of applications running in the Java virtual machine (VM). JVMTI is intended to provide a VM interface for the full breadth of tools that need access to VM state, including but not limited to: profiling, debugging, monitoring, thread analysis, and coverage analysis tools.

JVMTI will replace the now deprecated JVMPI and JVMDI in the next major release of J2SE.
