Couple of tests from AutoJ2DGraphics fails on WinXP-Nvidia GeForce 7600 with 6u4-b01 PIT build.

AlphaCompositeTest
AlphaCompositeComplexTest

Some of the acceptable rendering differences in the image are caused by 5051225 and minor differences in GradientPaint/TexturePaint rendering mentioned in 6588904. However, it also appears that the red rectangle is not hitting the correct pixels (one pixel wider in the golden image than in the test image). That part looks like a bug.

This is not reproducible with 6u3. Please take a look at the detailed report -
http://sqeweb.sfbay/2d/release/jdk6u4/pit/results/b01/WinXP-Nvidia_GeForce7600/Test_Report.html

To reproduce the bug, do the following -

1. Go to /net/sqe1.sfbay/quality2/2d/Mustang_2d_ws/2d/src/2D_AutoJ2DGraphics
2. Set PATH to GNUMAKE and set JAVA_HOME to D3D build.
3. give 'gnumake runauto'.

The results dir will be created under 2D_AutoJ2DGraphics and there will be a HTML report file inside that.
The differences seen in AreaTest seem to be due to the same reason as AlphaComposite.
