46     * Test program that demonstrates a bug in OpenJDK 1.7.0.60 (and
47     * probably in all other OpenJDK versions, too). To see the bug, simply run
48     * the 'main' program with OpenJDK. The bug makes the 'g2d.fill'
49     * method fail with the following exception:
50     *
51     * This bug is found in OpenJDK but also is present in OracleJDK
52     * if run with
53     * -Dsun.java2d.renderer=sun.java2d.pisces.PiscesRenderingEngine
54     *
55     * The bug is related to sun.java2d.pisces.PiscesCache constructor
56     * that accepts '(int minx,int miny,int maxx,int maxy)' arguments:
57     * the internal 'bboxX1' and 'bboxY1' are set to values one greater
58     * than given maximum X and Y values. Those maximum values are then
59     * later used in AAShapePipe' class 'renderTiles' method, where a
60     * Y/X loop eventually calls 'GeneralCompositePipe' class
61     * 'renderPathTile' method. In that method, the operation will
62     * eventually call 'IntegerInterleavedRaster' class
63     * 'createWritableChild' method with arguments:
64     *
65     * <UL>
66     * <LI>x=800
67     * <LI>y=0
68     * <LI>width=2 (this value is too high: should be 1)
69     * <LI>height=32
70     * <LI>x0=0
71     * <LI>y0=0
72     * <LI>bandList[]=null
73     * </UL>
74     *
75     * This calls for a sub-raster with bounds that fall outside the
76     * original raster, and therefore the 'createWritableChild' method
77     * correctly throws 'RasterFormatException'.
78     *
79     * The bug is closely related to the use of a custom Composite
80     * implementation, which are quite rare. The application where this
81     * bug was first detected implements a high-quality PDF rendering
82     * engine that needs custom Composite operations to properly
83     * implement PDF advanced color blending and masking operators.
