I have a custom Icon that uses TexturePaint as a paint and calls fillPolygon for a Graphics2D object.
This code works fine on JDK6 and JDK7, but it doesn’t work on JDK8 with 64-bit Linux (I tried the latest JDK1.8 on 64-bit Linux). On Windows, this works fine with JDK8.
The output of the java -version for the JDK used to reproduce the problem.
java version "1.8.0_25" Java(TM) SE Runtime Environment (build 1.8.0_25-b17) Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)
Code to reproduce the problem:
import java.awt.*; import java.awt.image.*; import javax.swing.*; public class TexturePaintIconTest { private static class CustomIcon implements Icon{ private static final int[] sXArray = new int[]{2, 5, 7, 12, 12, 4, 1, 1, 2}; private static final int[] sYArray = new int[]{4, 4, 2, 2, 11, 11, 8, 5, 4}; private static final int sNumberOfPoints = 9; @Override public void paintIcon(Component c, Graphics g, int x, int y) { g.translate(x,y); Graphics2D g2d = (Graphics2D) g; Color fillColor = new Color( 140, 25, 25, 35); g2d.setPaint(createPatternPaint(fillColor)); g2d.fillPolygon(sXArray, sYArray, sNumberOfPoints); g.translate(-x, -y); } private Paint createPatternPaint(Color color ){ int[] colors = new int[]{color.getRGB(), 0}; IndexColorModel colorModel = new IndexColorModel(1, 2, colors, 0, true, -1, DataBuffer.TYPE_BYTE); BufferedImage image = new BufferedImage(2, 2, BufferedImage.TYPE_BYTE_INDEXED, colorModel); DataBufferByte dataBuffer = (DataBufferByte) image.getRaster().getDataBuffer(); byte[] data = dataBuffer.getData(); data[0] = 0; data[1] = 1; data[2] = 1; data[3] = 0; return new TexturePaint(image, new Rectangle(2, 2)); } @Override public int getIconWidth() { return 16; } @Override public int getIconHeight() { return 16; } } public static void main(String[] args) { EventQueue.invokeLater(new Runnable() { @Override public void run() { JFrame testFrame = new JFrame("TestFrame"); JLabel label = new JLabel("Label with icon", new CustomIcon(), SwingConstants.LEFT); testFrame.add(label); testFrame.pack(); testFrame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE); testFrame.setVisible(true); } }); } }
Running the main method results in the following error
Exception in thread "AWT-EventQueue-0" java.lang.InternalError: Surface not cachable at sun.java2d.xr.XRPaints$XRTexture.getAccSrcSurface(XRPaints.java:211) at sun.java2d.xr.XRPaints$XRTexture.isPaintValid(XRPaints.java:224) at sun.java2d.xr.XRPaints.isValid(XRPaints.java:75) at sun.java2d.xr.XRSurfaceData.getMaskFill(XRSurfaceData.java:205) at sun.java2d.SurfaceData.validatePipe(SurfaceData.java:675) at sun.java2d.xr.XRSurfaceData.validatePipe(XRSurfaceData.java:123) at sun.java2d.SunGraphics2D.validatePipe(SunGraphics2D.java:446) at sun.java2d.pipe.ValidatePipe.validate(ValidatePipe.java:55) at sun.java2d.pipe.ValidatePipe.fillPolygon(ValidatePipe.java:147) at sun.java2d.SunGraphics2D.fillPolygon(SunGraphics2D.java:2389) at com.luciad.internal.lucy.map.TexturePaintIconTest$CustomIcon.paintIcon(TexturePaintIconTest.java:22)
I already searched in the Java error database ( official and openjdk one ), but did not find an error report that could explain this. Am I something wrong with my custom icon, or did I come across a JDK error?
