Using Swing Parser locks up.

Question

I'm using the Swing Parser class to read all the text content of an HTML page off the web.
I override the parse() method. I then setup my URL connection and setup my BufferedReader, and then I call super.parse(br);
I run this code every 5 seconds in a thread. After some time my java.exe process consumes almost 100% of my CPU and my java program is blocked.
It seems to me that my program is locking up somwhere inside the super class method parse().
I'm open to any advice or suggestions. I'm using jdk1.3.1_01 and windows xp. I know XP isn't exactly Java friendly. I'm not sure if that is the cause.
Any help or advice is gretly appreciated.

Answer 1

Here is my entire program. I re-read the Swing article on HTML and as you can see, there is minimal code here.
Could it be that the particular web site I'm trying to visit maybe denies me access if I keep hitting it?
After awhile my java process stops running and is in some kind of loop and uses 90+% cpu.
Thanks for any insight.
