Hi,

just wondering if anyone did some nice code which
uses the sun.reflect.ClassFileAssembler
and sun.reflect.AccessGenerator

BTW: Sun left a spelling error in that ClassFileAssembler
class: emitBoxingContantPoolEntries

Cheers

Hopefully not, given that Sun themselves say you shouldn't use classes
in the sun.* packages.

Just another reason to avoid using classes you're not supposed to in
the first place.

There's alternative free packages around. Most popular seems BCEL, I
have also played with ASM (http://asm.objectweb.org/) which seems more
lightweight. Implementing something similar to C#'s whatstheirnames
(delegates?), i.e. turning an (object, methodname) into an
implementation of Runnable was very straightforward.

Next project will be dynamic proxies that can additionally specify a
superclass.
