First, the AnonymousClassLoader  in the  hg repository  has several 
limitations.
See the thread:
http://mail.openjdk.java.net/pipermail/mlvm-dev/2008-April/000056.html

*Be it as it may*, the AnonymousClassLoader only takes an hostClass at 
construction.
And you can use setClassFile() and then loadClass() to load an anonymous 
class.
You perhaps browse the source code too kickly,
the constructors are definined in the middle  of the  file not in the 
beginning,
it's trouble me too the first time i've read that code.

Ok, you want to be able to compile the sources without the package java.dyn.

I've perhaps found why there is no difference in your test.
I've re-read the code of your ruby Classoader and someting is weird,
the last instruction of the static block should be

ANONYMOUS_SUPPORTED = true;
and not
ANONYMOUS_SUPPORTED = false;
