Comment 2 Aaron Hoffer CLA 2011-09-23 21:29:19 EDT 
I get this same error frequently. I am unable to isolate why it occurs. I have attached my log file that shows the last few days of history. It contains multiple examples of the error. I am also attaching a screen shot of the threads as they show up in the Debug view; the state of that window look out-of-the-ordinary. Here is what I know:

1. Run debug configuration of the application.
2. The application's window opens (it is a GUI app using GLUT). 
3. The application stops executing and no breakpoints are hit.
4. The threads in the Debug window do not show a call stack. There are three threads shown as part of the .exe process. The first two say "(Running: Container). The third threads says "(Running: User Request). The call stack is not displayed.

Comment 4 Aaron Hoffer CLA 2011-09-23 21:33:32 EDT 
I forgot to add steps 4 and 5 in the previous comment.

4. Click the red square to stop debugging.
5. My applications GUI window closes.
6. Eclipse opens a dialog box and explains "Clear Breakpoints Status" experienced a java null pointer exception.

I was using at least one conditional breakpoint, but it is hard to tell if that was a factor in the dialog box opening.
