Run the swingset's JTable demo.
Click on one of the entries in the "Favorite Color" column.
When the combobox opens, press the PageUp or PageDown key.
An enormous stack trace will be dumped to the screen.

It looks like an infinite loop. I have attached the stack trace I got.
It seems to be reproducible 100% of the time.

I was running on an Ultra10 (not a creator).
