Java Fun: When all you have is a hammer...

I ought to be ashamed, but I was bored and lazy, so I thought I'd test my somewhat dormant Java skills. Can you tell me (without running it) what this code does?

  Method[] methods = Foo.class.getMethods();
  String source = FileUtils.readFully(new FileReader(
    "src/main/java/"
      + Foo.class.getCanonicalName().replaceAll(
        "\\.", "/") + ".java"));
  PrintStream out = System.out;
  for (Method method : methods) {
   Matcher matcher = Pattern.compile(
     "public (\\S+?) " + method.getName() + "\\((.*?)\\)",
     Pattern.DOTALL | Pattern.MULTILINE).matcher(source);
   if (matcher.find()) {
    String ret = matcher.group(1);
    String params = matcher.group(2);
    out.printf(" public %s %s(", ret, method.getName());
    out.print(params);
    out.print(") {\n  ");
    if (!"void".equals(ret)) {
     out.print("return ");
    }
    out.print("foo.");
    out.print(method.getName());
    out.print('(');
    if (!StringUtils.isEmpty(params)) {
     out.print(StringUtils.join(CollectionUtils.collect(
       Arrays.asList(params.split(",\\s*")),
       new Transformer() {
        public Object transform(Object input) {
         return ((String) input).split(" ")[1];
        }
       }), ','));
    }
    out.println(");\n }\n");
   }
  }

I'll post the equivalent Groovy (and maybe JavaScript) later. I imagine I can do it in a single statement function. I don't miss Java very much.
