Jamaica
Jamaica, the JVM Macro Assembler, is an assembly language for JVM bytecode programming. It uses Java syntax to define a JVM class except for the method body that takes bytecode instructions, including Jamaica‘s built-in macros. In Jamaica, bytecode instructions use mnemonics and symbolic names for all variables, parameters, data fields, constants and labels. Jamaica is a simplified JVM assembly language. It does not support inner classes. Variables are all method-wide and are strongly-typed. Jamaica is a language facade for a Java class creation API, JavaClassCreator. This API closely mimics the Jamaica language, allows users to define a Java class with the same flow, and supports all the Jamaica instruction set and macros.
