I highly doubt that the FrameBuffer.blit() - int[] contains bug. For the Texture version is ok, but if i use the int[] version, no matter how I do it, I always get java.lang.ArrayIndexOutOfBoundsException: 9 saying that no such item at index 9. But obviously I'm passing an image with a length of 307200. If you can help, the following program will reproduce the error.

Te honest, any five-year-period in life is a duration where it begin to strongly affect some group of people, and jPCT is affecting the world. We are all the kind that don't give things up easily, that's something I am proud of jPCT (of course and of all of you)
