        Description

        FULL PRODUCT VERSION :
        java version "1.6.0_20"
        Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
        Java HotSpot(TM) 64-Bit Server VM (build 16.3-b01, mixed mode)

        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.
