A DESCRIPTION OF THE PROBLEM :
The following code:

        BufferedImage image = null;
        try {
            image = ImageIO.read(imageUrl);
        } catch (Exception e) {
            log.error("Unable to read image file: " + fileName);
            e.printStackTrace();
        }

occasionally throws an exception out of the blue:

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Cannot reproduce it on second Ubuntu 32bit machine.

Behaviour seems to be less frequent when I run the JVM with less (!) memory in -Xmx

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Load the buffered image (same code works fine many times, but not always)
ACTUAL -
Exception is thrown from deep below

ERROR MESSAGES/STACK TRACES THAT OCCUR :
java.util.ConcurrentModificationException


REPRODUCIBILITY :
This bug can be reproduced often.
