Weird! A Java assembler! From the examples:
public class CFirstCls
{
int count;
public CFirstCls() {
iconst_0
putfield count int
return
}
public void inc(int amount) {
getfield count int
iload amount
iadd
putfield count int
return
}
public void printSelf() throws IOException {
getstatic System.out PrintStream
aload this // same as aload_0
invokevirtual PrintStream.println(Object)void
return
}
public String toString() {
ldc "It's only me!"
areturn
}
}

> Jamaica, the JVM Macro Assembler, is an easy-to-learn and easy-to-use
> 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.
>
> Why Jamaica? Even with the rigid JVM architecture and verification,
> creating JVM classes at bytecode level is still highly risky and
> error-prone. With Jamaica, you can quickly experiment dynamically
> creating classes; once done, mechanically convert the Jamaica source
> code into JavaClassCreator API calls. Jamaica is currently the only
> macro assembler for JVM, and serves this purpose very well.
