[kaffe] Kaffe VM Memory Footprint Optimization

[L'Archeveque, Regent]

Hi all, 
 
I try to reduce the memory footprint of the Kaffe VM.  Based on old mailing list messages, It seems that targeting 1 Meg RAM device was possible with Java.  I have made a lot of tests in order to reduce the footprint as much as possible.  I applied the tips mentionned in the kaffe.embedded FAQ but with a minimal impact.  A simple program (see below the code and the GC verbose messages and top snapshot) requires more memory than what I expected (based on my readings).  
Does someone have some tips or references?  Where can I find the list of FEATURE handled by kaffe (FEATURE to be disabled or enabled with configure command)?
Is it possible to use kaffe with embedded devices with less than 8 Megs or should I use CDC or CLDC?
 
 public static void main(String[] args) {
  int i = 0;
  while (true) {
   System.out.println("i = " + i++);
   try {
    Thread.sleep(100);
   } catch (InterruptedException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   }
   System.gc();  // Just for the test.
  }
 }
