      Description



      Name: boT120536 Date: 03/12/2001


      java version "1.3.0"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0-C)
      Java HotSpot(TM) Client VM (build 1.3.0-C, mixed mode)

      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:

      All other theads named "Thread-<n>" show: "waiting on monitor"
