Summary: Dr. Java - Windows Vista conflict

Initial Comment:
I am using drjava-stable-20090821-r5004, Java 6, and Windows Vista (Service Pack 1)

When Dr. Java tries to call greyscale() method "Pixel[] pixelArray = this.getPixels();"
Windows XP runs "Picture.java" fine.  When you try and run the same class in Windows Vista,
the following error occurs:

Increase Maximum Heap Size?
Your program ran out of memory.  You may try to enter a larger maximum heap size for the interactions JVM.
The maximum heap size is currently not set, implying the system's default.  A restart is required after changing
this setting.   "default"


This is the code I'm trying to compile and run (picture.java):

import java.awt.*;
import java.awt.font.*;
import java.awt.geom.*;
import java.awt.image.BufferedImage;
import java.text.*;
import java.util.*;
import java.util.List; // resolves problem with java.awt.List and java.util.List
