I'd like to see bug 4332685 reopened, as I am still seeing it, even though it
has been marked as closed.

Occasionally, perhaps one time in twenty, the JVM will completely freeze, and
have to be killed manually. Looking through a full stack dump shows that the
MediaTracker class is waiting forever:

"AWT-EventQueue-0" prio=7 tid=0x7748e0 nid=0x5df waiting on monitor [0x8fbf000..0x8fbfdc8]
at java.lang.Object.wait(Native Method)
at java.awt.MediaTracker.waitForID(Unknown Source)
at javax.swing.ImageIcon.loadImage(Unknown Source)
at javax.swing.ImageIcon.<init>(Unknown Source)
        [snip]
at java.awt.EventDispatchThread.run(Unknown Source)

The problem has only ever been seen when running our application on a dual
processor NT4 machine.

Customer seems to have run into the same problem. Application is completely
hung and has to be "^C"-ed. Here is a snippet from a stacktrace, that was
drawn while hung:
