I've found this issue happens intermitently on my setup:
Ubuntu 13.04 64-bit
OpenJDK Runtime Environment (IcedTea 2.3.10) (7u25-2.3.10-1ubuntu0.13.04.2)
OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)
I get an intermitent crash when decoding JPEGs, decoding in several
threads.
Thread pool is created thus:
ExecutorService threadpool =
Executors.newFixedThreadPool(Runtime.getRuntime().availableProcessors()+1);
Image decode tasks added this:
ImageScaler scaler = new ImageScaler(size);
threadpool.submit(scaler);
ImageScaler class is:
private class ImageScaler extends SwingWorker<ImageIcon, String> {
private int size;
public ImageScaler(int size) {
this.size = size;
}
@Override
public ImageIcon doInBackground() {
LOGGER.log(Level.FINE,
"Loading image: "+url);
ImageReader ir;
//create a new instance of imageReader
synchronized(sync){
Iterator<ImageReader> it =
ImageIO.getImageReadersByMIMEType("image/jpeg");
ir = it.next();
if (ir == null) {
LOGGER.log(Level.SEVERE,
"No image reader found
for JPEGs");
System.exit(1);
}
ImageReaderSpi spi =
ir.getOriginatingProvider();
try {
ir = spi.createReaderInstance();
} catch (Exception e) {
LOGGER.log(Level.SEVERE,
"Could not create new
JPEG reader instance", e);
return null;
}
}
//Load the image from the URL (could be local or HTTP)
BufferedImage image;
try {
[...]
File cacheDir = new File (strCacheDir);
cacheDir.mkdirs();
URL u = new URL(url);
FileCacheImageInputStream fcis = new
FileCacheImageInputStream(
u.openStream(), cacheDir);
ir.setInput(fcis);
image = ir.read(0);
fcis.close();
} catch (Exception e) {
LOGGER.log(Level.WARNING,
"Could not read image "+url, e);
return null;
} catch (OutOfMemoryError e) {
LOGGER.log(Level.WARNING,
"Out of memory reading image:
"+url, e);
return null;
} finally {
ir.dispose();
}
return new ImageIcon(resizeImage(image, size));
}
@Override
protected void done() {
if (isCancelled())
return;
ImageIcon icon = null;
try {
icon = get();
} catch (Exception ignore) {}
if (icon == null) {
LOGGER.log(Level.WARNING,
"Scaled image is null: "+url);
return;
}
rendered = icon;
renderedSize = size;
mPcs.firePropertyChange(PNAME_RENDEREDICON, 0, 1);
}
}
The crash actually occurs in ICC_Profile code. I get intermitent colour
issues with decoded JPEGs where the image is totally mid-green except
for areas that are dark which tend to black. Is there an issue in the
colour code for multi-threaded decode? I've done my best to create an
image reader in a thread-safe way.
I've attached the crash log file.

~~~ PS
When I tried to compile BugIIO.java on openjdk-6 and run it on openjdk-6, the
program finishes normally (no crash).
To clarify:
1. This bug affect OpenJDK 7 (7~b147-2.0-0ubuntu0.11.10.1) (tested on
oneiric).
2. This bug does *not* affect OpenJDK 6 (6b23~pre11-0ubuntu1.11.10) (tested
on oneiric).
