W5100 send data writes TX-buffer?

Hi,

I use an Arduino Uno and the latest Ethernetshield(inkl. microSD). Here's my Sketch:

#include <SPI.h>
#include <Ethernet.h>


byte mac[] = { 
  0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED};
byte ip[] = { 
  172,20,162,33 };
byte gateway[] = {
  172,20,161,1};	
byte subnet[] = { 
  255, 255, 252, 0 };

byte server[] = { 
  172,20,162,32 }; 


Client client(server, 3009);

void setup() {
  Ethernet.begin(mac, ip);
  // give the ethernet module time to boot up:
  delay(1000);
}

void loop() {
 client.flush();
 client.connect();
 client.println("TEST");
 client.flush();
 client.stop();
   
}

All it should do is send a simple "TEST". I wrote a Java-programm to display the send data. Here's the output

It seems that my arduino send the whole cache to my PC. The flush() only affects the RX-Buffer. As you can see i tried the Pachube-Example before, maybe thats why it shows up. Any suggestions what goes wrong here?
