Kevin,

I have run the program on two other machines, a Pentium 4 1.8 Ghz running Windows XP and a Pentium 4 800 Mhz running Linux. All the machines that I have tested on have J2SDK 1.4.1 installed. I have looked further into the problem and am more confused now than ever. I have narrowed it down to one line of code, the recieveFrame method recieves a frame (of MSG type) and then processes it. It then calls the listener.recieveMSG(m) method. Just before this line is executed I output the message number and it is correct, but after in the message listener (TestBombProfile) the message recieved by recieveMSG has an incorrect number.

The error occurs at about line 500 in the Channel.java file (receiveFrame method). I added three debug outputs two in the receiveFrame method - one at the begining of the MSG type part (it outputs the message number) and the other just before the listener.recieveMSG(m) method is called (about line 500). I also put an output at the begining of the recieveMSG method (Also outputs the message number). Here follows what output should be recieved (for message number 4):
recieveFrame: recieved frame no 4
Channel: removed message 4
TestBombProfile: recieved message no. 4

I will attatch the results that I got as well as the example files. You will notice that I got very strange results, the first few messages don't seem to call the listener but the after a few they call the listener but with the wrong object (they call it the number of times that it was missed with the latest message object). To me it looks like a standard method call passing a parameter, it does not make sence to me that it does what it does. The error I revieved on the client side is:
SEVERE: Incorrect message number: was 3; expected 1
and then the client aborted the session.

Before you think that it has something to to do with the listener not being registered in time, I have seen it happen where the first few messages are correct but then the problem occurs later on.

What pc are you running, what operating system, and what version of JDK is installed? I connot understand how I get the same problem everytime but you don't.

Please try the test again and let me know how it goes.

Thanks,
Sean
