Test fails with same error for jdk 1.8.0_60 b27. Please check if backport is needed.

> Test fails with same error for 8u66b10 also That is no surprise. This bug is not a regression.

The problem is caused due to this part of code in jdk/src/java.desktop/unix/classes/sun/java2d/xr/XRDrawImage.java :- public class XRDrawImage extends DrawImage { protected void renderImageXform(SunGraphics2D sg, Image img, AffineTransform tx, int interpType, int sx1, int sy1, int sx2, int sy2, Color bgColor) { SurfaceData dstData = sg.surfaceData; SurfaceData srcData = dstData.getSourceSurfaceData(img, SunGraphics2D.TRANSFORM_GENERIC, sg.imageComp, bgColor); int compRule = ((AlphaComposite) sg.composite).getRule(); float extraAlpha = ((AlphaComposite) sg.composite).getAlpha(); -------------------------------------------------------------------------------------------- } } Where the Type Cast is being done by AlphaComposite but sinceTest is setting XORMode so we can put a check before typecasting that if it is an instance of AlphaComposite as below :- public class XRDrawImage extends DrawImage { protected void renderImageXform(SunGraphics2D sg, Image img, AffineTransform tx, int interpType, int sx1, int sy1, int sx2, int sy2, Color bgColor) { SurfaceData dstData = sg.surfaceData; SurfaceData srcData = dstData.getSourceSurfaceData(img, SunGraphics2D.TRANSFORM_GENERIC, sg.imageComp, bgColor); if ( sg.composite instanceof AlphaComposite) { //Adding this check before typecasting int compRule = ((AlphaComposite) sg.composite).getRule(); float extraAlpha = ((AlphaComposite) sg.composite).getAlpha(); ------------------------------------------- } }
