Bug#556978: sun-java6-bin: javax.imageio.ImageIO.write prints stack trace if file un-writable.

[Timothy Baldwin <T.E.Baldwin99@members.leeds.ac.uk>]

Package: sun-java6-bin
Version: 6-16-1
Severity: normal


The following program prints on stderr:

java.io.FileNotFoundException: /test.png (Permission denied)
        at java.io.RandomAccessFile.open(Native Method)
        at java.io.RandomAccessFile.<init>(RandomAccessFile.java:212)
        at javax.imageio.stream.FileImageOutputStream.<init>(FileImageOutputStream.java:53)
        at com.sun.imageio.spi.FileImageOutputStreamSpi.createOutputStreamInstance(FileImageOutputStreamSpi.java:37)
        at javax.imageio.ImageIO.createImageOutputStream(ImageIO.java:393)
        at javax.imageio.ImageIO.write(ImageIO.java:1514)
        at Fail.main(Fail.java:10)
--- BELOW HERE ---
java.lang.NullPointerException
        at javax.imageio.ImageIO.write(ImageIO.java:1523)
        at Fail.main(Fail.java:10)

The line "--- BELOW HERE ---" should be the first output.

import java.io.*;
import javax.imageio.ImageIO;
import java.awt.image.*;

public final class Fail {
  public static void main(String[] args) throws java.io.IOException {
    try {
      File out = new File("/test.png");
      BufferedImage image = new BufferedImage(100, 100, BufferedImage.TYPE_INT_RGB);
      javax.imageio.ImageIO.write(image, "PNG", out);
    } catch (Throwable e) {
      System.err.println("--- BELOW HERE ---");
      e.printStackTrace();
    }
  }
}
