It is a nice example, and I've done something similar myself (on
smtpauth, and w3 if I remember).

Like this class which is a bit of a classic.
http://docs.spring.io/spring/docs/2.5.x/api/org/springframework/aop/framework/AbstractSingletonProxyFactoryBean.html
and has been described as everything wrong with Java in a single class.
None the less, I think you are hitting a strawman here; if Emacs went
entirely lexically bound, I don't think that it necessarily follows that
elisp will turn into Java.
