I have a Canvas contained within a ScrollPane. The Canvas is very tall, over
33000 pixels. I'm using the Canvas to display text which I render using
the Canvas' paint() method. As I scroll the Canvas within the ScrollPane
and scroll past position 32767, the damage rect I get back in the paint()
method has a y-coordinate which is negative. Also, my blue Canvas also flakes
out and either isn't as tall as it should be or it turns gray.


Run the attached test case and scroll down. As you pass location 30000, it
will start printing out the y-coordinate of the damage rect. Notice when it
goes negative, and notice the Canvas within the ScrollPane. The color will
also change from blue to gray.

I tried overriding the Maximum size, since I saw that by default it is set to
Short.MAX_VALUE but that didn't help. This bug is currently breaking one
piece of functionality within HotJava Views, and has the potential to screw up
at least 2 more. Hopefully there is a workaround that I'm missing.
