Java Bytecode Wizardry: Supercharge Your Apps Without Touching the Source Code
Java bytecode instrumentation allows modifying compiled Java classes without changing source code. It uses Java Agents and libraries like ASM or ByteBuddy to manipulate bytecode at runtime. This technique enables adding features like timing, logging, profiling, and security checks to applications dynamically. It's powerful but should be used carefully to avoid complexity and performance issues.
