/**
* 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:
*
* This bug is found in OpenJDK but also is present in OracleJDK
* if run with
* -Dsun.java2d.renderer=sun.java2d.pisces.PiscesRenderingEngine
*
* 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'.
*
* 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.
