  /**
   * Test program that demonstrates a bug in OpenJDK 1.7.0.60 (and
   * probably in all other OpenJDK versions, too). To see the bug, simply run
   * the 'main' program with OpenJDK. The bug makes the 'g2d.fill'
   * method fail with the following exception:
   *
   * <PRE>
   * Exception in thread "main" java.awt.image.RasterFormatException: (x + width) is outside raster
   * at sun.awt.image.IntegerInterleavedRaster.createWritableChild(IntegerInterleavedRaster.java:467)
   * at sun.awt.image.IntegerInterleavedRaster.createChild(IntegerInterleavedRaster.java:514)
   * at sun.java2d.pipe.GeneralCompositePipe.renderPathTile(GeneralCompositePipe.java:106)
   * at sun.java2d.pipe.AAShapePipe.renderTiles(AAShapePipe.java:201)
   * at sun.java2d.pipe.AAShapePipe.renderPath(AAShapePipe.java:159)
   * at sun.java2d.pipe.AAShapePipe.fill(AAShapePipe.java:68)
   * at sun.java2d.pipe.PixelToParallelogramConverter.fill(PixelToParallelogramConverter.java:164)
   * at sun.java2d.pipe.ValidatePipe.fill(ValidatePipe.java:160)
   * at sun.java2d.SunGraphics2D.fill(SunGraphics2D.java:2466)
   * at OpenJDKFillBug.main(OpenJDKFillBug.java:55)
   * </PRE>
   *
   * The bug is OpenJDK specific. This program runs with Oracle JDK
   * just fine (it still does not do anything sensible, but it does
   * not fail with a RasterFormatException, either).
   *
   * <P>
   *
   * The bug is related to sun.java2d.pisces.PiscesCache constructor
   * that accepts '(int minx,int miny,int maxx,int maxy)' arguments:
   * the internal 'bboxX1' and 'bboxY1' are set to values one greater
   * than given maximum X and Y values. Those maximum values are then
   * later used in AAShapePipe' class 'renderTiles' method, where a
   * Y/X loop eventually calls 'GeneralCompositePipe' class
   * 'renderPathTile' method. In that method, the operation will
   * eventually call 'IntegerInterleavedRaster' class
   * 'createWritableChild' method with arguments:
   *
   * <UL>
   * <LI>x=800
   * <LI>y=0
   * <LI>width=2 (this value is too high: should be 1)
   * <LI>height=32
   * <LI>x0=0
   * <LI>y0=0
   * <LI>bandList[]=null
   * </UL>
   *
   * This calls for a sub-raster with bounds that fall outside the
   * original raster, and therefore the 'createWritableChild' method
   * correctly throws 'RasterFormatException'.
   *
   * <P>
   *
   * The bug is closely related to the use of a custom Composite
   * implementation, which are quite rare. The application where this
   * bug was first detected implements a high-quality PDF rendering
   * engine that needs custom Composite operations to properly
   * implement PDF advanced color blending and masking operators.
