JVM Tools - Essential Resources for Java Virtual Machine Development

Performance Monitoring and Profiling

JVM TI (JVM Tool Interface) - A native programming interface for inspecting and controlling the state of a running Java application.
async-profiler - A low overhead sampling profiler for Java featuring flame graphs, ideal for performance analysis.
YourKit Java Profiler - A feature-rich Java profiler for in-depth memory and CPU analysis, helping developers optimize their applications.
VisualVM - A visual tool for profiling Java applications, integrating several JDK command-line tools and lightweight profiling capabilities.

JDK Mission Control - A powerful profiling and diagnostics tools suite for the JVM, offering advanced analysis features.
JRebel - A JVM plugin that eliminates the need for redeployment during development, dramatically improving developer productivity.
BTrace - A safe, dynamic tracing tool for the Java platform, allowing for runtime instrumentation of Java programs.

Eclipse Memory Analyzer (MAT) - A fast and feature-rich Java heap analyzer that helps identify memory leaks and optimize memory usage.
Google Allocation Instrumenter - A Java agent that tracks object allocations, helping developers understand memory consumption patterns.
Java Agent for Memory Measurements (JAMM) - A Java agent for measuring actual object memory use, including JVM overhead, to improve memory efficiency.

ASM - A Java bytecode manipulation and analysis framework that allows developers to modify existing classes and create new ones.
Byte Buddy - A runtime code generation library that enables creating highly dynamic Java classes without compiler support.
cglib - A high-level API to generate and transform Java bytecode, useful for creating proxies and enhancing classes at runtime.

Apache Maven - A popular build automation and project management tool that simplifies the process of managing project dependencies.
