"Exception in thread "Thread-2" java.lang.OutOfMemoryError: Java heap space

If you haven't already, try increasing the heap by using the java command option -Xmxnm, where n is the heap in MB. Assuming you are using Win 32 XP, you'll find that your maximum value will be somewhere between 1200MB and 1700MB (approx.) This is a limitation of Windows, not much can be done to change it.

You can use this command with varying values of MB to find your maximum:

java -Xmx1330m -version
