A bzipped tar archive containing two images demonstrating the bug and the java
source file used to create these images

Calling copyArea with a negative horizontal distance results in garbage being
draw to the immediate left of the exposed area.

Positive horizontal distances work correctly, as do positive and negative
vertical distances.

Attached is a bzipped tar file containing two images that demonstrate this bug
as well as the java source used to create these images.  One image is from
IcedTea6, the other from Oracle's HotSpot7.  The oval on the bottom left is the
one drawn using a negative horizontal distance.

java version "1.6.0_33"
OpenJDK Runtime Environment (IcedTea6 1.13.5) (Gentoo package
OpenJDK 64-Bit Server VM (build 23.25-b01, mixed mode)
