Lincoln, try doing an os.flush(); right after your os.print of the echo
request.  I suspect that the close of the Socket is not flushing the 
output as is apparently happening in the JDK.  Though adding the os.flush();
fixed the behavior using gcj on my platform, it'll take a bit more 
investigation to determine what libgcj should be doing.

Thanks for reporting this!
