FULL PRODUCT VERSION :
java version "1.4.2_06"
java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_06-b03
Java HotSpot(TM) Client VM (build 1.4.2_06-b03, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Windows XP SP1

A DESCRIPTION OF THE PROBLEM :
http://web.mit.edu/charvak/Public/Java/javaerror.GIF shows what's left on the command prompt when appletviewer crashes. I wrote the applet located at http://web.mit.edu/charvak/Public/Java/ and it runs on Mac OS9 and MIT's UNIX-based Athena system, but won't work on Windows XP.

Specifically, the program performs as expected for very small inputs like A1=2 and D1=2. However, it only runs a few times and crashes eventually.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Open http://web.mit.edu/charvak/Public/Java/AA.html. Hit clear and then type 2's in the boxes that contained A1 and D1. Hit "calculate probs" and the program will run. Repeat that a total of 8 times and the applet will crash. In theory, it should perform the same every time.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I was expecting the applet to run the same every time I hit "calculate probs" and with numbers on the order of 10 as inputs.
ACTUAL -
The applet seems to die after performing a certain amount of computation. It can take two 1's and process them about 40 times. Two 2's will kill it after 8 tries. Large enough numbers kill it immediately.
