Java SE (Java Platform, Standard Edition)

Hi. I�m working on a simple paint program and I�m having some trouble with the bucket or filling tool. This tool must fill any shape drawn by the user with the current color (the user clicks on a given point and the tool replaces the color of the area surrounding that point with the new color). I have used several algorithms for this (flood fill, boundary fill, etc..) but non of them seem to work. The recursive ones cause an out of stack or out of memory error, and iterative versions are too slow and never finish (only good for filling very small areas) .
I was wondering if there is any way in Java to go around this.
Thanks.
