Yeah, It is new in jdk 1.4, but this "new" api is not supposed to 
replace the "old" one.
It is a lower-level API, somewhat less user-friendly, but faster and 
more powerful
for this kind of packet-based, low-level applications. Also, you don't 
need to use
threads, you've the C "poll()" function available.

Makes sense.  Actually, it wouldn't be that difficult to update the 
code. The
toPacket could be replaced to write directly to a buffer, so it actually 
becomes
much simpler, no more exceptions, allocations, ...

 public void toPacket(ByteBuffer bb, int requestId, byte suspendPolicy)
   {
     bb.put(suspendPolicy);
     bb.putInt(1);
     bb.put(_eventKind);
     bb.putInt(requestId);
     _writeData(bb);
   }
