This library makes Java bytecode manipulation simple. It enables Java programs to define a new class at runtime and to modify a class file when the JVM loads it.

Unlike other bytecode editors, Javassist provides two levels of API: source level and bytecode level. With the source-level API, users can edit a class file without knowledge of the specifications of the Java bytecode.
