But decompiling the Java bytecode generated by JRuby would be pretty much 
impossible because it has crazy things in it like call-site caches. The 
reason why the Java bytecode can be decompiled into the equivalent Java 
source code is because (a) the Java bytecode keeps a lot more information 
around, (b) because Java is the C of the JVM, and (c) because in Java, 
the JVM does the optimization, not the compiler.
