Tilman Hausherr commented on PDFBOX-4581:
-----------------------------------------
Yes PDFDebugger renders into a BufferedImage.
{quote}
In my application I currently use a different PDF renderer.
{quote}
Which one?
Transparency groups are very difficult and it took us many years to get them
mostly right (PDFBOX-3000).
I could catch the exception just so that you can see how it looks.
In the meantime, I was asked to provide a stand alone case. Could you please
run this test code on your machine and tell if the error occurs?
{code}
public class CompositeTest
{
private static JPanel getTestPanel()
{
JPanel panel = new JPanel()
{
@Override
protected void paintComponent(Graphics g)
{
g.setColor(Color.white);
g.fillRect(0, 0, getWidth(), getHeight());
BufferedImage bim = new BufferedImage(getWidth() / 2,
getHeight() / 2, BufferedImage.TYPE_INT_ARGB);
drawFlag(bim);
Graphics2D g2d = (Graphics2D) g;
g2d.setComposite(AlphaComposite.getInstance(AlphaComposite.SRC));
g2d.drawImage(bim, null, getWidth() / 4, getHeight() / 4);
}
private void drawFlag(BufferedImage bim)
{
Graphics2D g = (Graphics2D) bim.getGraphics();
g.setColor(Color.black);
g.fillRect(0, 0, bim.getWidth(), bim.getHeight() / 3 + 2);
g.setColor(Color.red);
g.fillRect(0, bim.getHeight() / 3, bim.getWidth(),
bim.getHeight() / 3 + 2);
g.setColor(new Color(0xFFD700));
g.fillRect(0, bim.getHeight() / 3 * 2, bim.getWidth(),
bim.getHeight() / 3 + 2);
g.dispose();
}
};
return panel;
}
public static void main(String[] args) throws Exception
{
SwingUtilities.invokeLater(new Runnable()
{
@Override
public void run()
{
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
frame.add(getTestPanel());
frame.pack();
frame.setSize(600, 600);
Dimension paneSize = frame.getSize();
Dimension screenSize = frame.getToolkit().getScreenSize();
frame.setLocation((screenSize.width - paneSize.width) / 2,
(screenSize.height - paneSize.height) / 2);
frame.setTitle("Test");
frame.setVisible(true);
}
});
}
}
{code}
My initial code was drawing a cross in some arbitrary color, but then I
realized that it might be some evil symbol that I haven't heard about. So now
it draws a German flag. This can easily be changed into e.g. a French flag or
an Italian flag.

> The same exception came up in the comments to PDFBOX-2905.
> Seems to be the same problem as in
> [JDK-6689349.|https://bugs.openjdk.java.net/browse/JDK-6689349]
> I reproduced this with PDFBox 2.0.13, 2.0.15 and 3.0.0-SNAPSHOT. And also
> with an oracle jdk.1.8.0_201, open jdk 1.8.0_212 and open jdk 11.0.1.
> I've attached an example maven project using the same PDF as in PDFBOX-2905.
