The most sophisticated tool I remember for reducing static binary size
was from Adam Megacz.  I'm pretty sure he released the code for it but I
couldn't find it (after only a single google attempt).

Here's a reference to it:
http://gcc.gnu.org/ml/java/2002-02/msg00202.html

It sounds wild:
  "Yeah, it's actually a Java program that does reachability analysis on
  the bytecode version of your program, and then spews out a linker
  script that will drop the unreachable methods. It also has some hacks
  to know what methods inside libgcj are invoked by native methods. I
  got HelloWorld down to 133kb gzipped."

If you search and find any more references to this (or contact Adam),
post your findings to this list.

Thanks,
