This is from Oracle, a Java licensee.
The Oracle bug number is 697005.
 
This bug occurs with JDK 1.1.6FCS. but didn't occur with JDK1.1.4.
Please consider this a regression problem, and examine it ASAP.
 
We now don't have a simple Java test case that can reproduce this problem, so
I can only describle this bug's behavior.
 
It occurs everytime when calling Java method to load a new component,
which is installed image. The reason is: JDK is already packaged with a old
version of MSVCRT.DLL (version 4.20.6164) and it conflicts with the image
loading. If we change it to version 4.20.6201, it works fine. But if the old
version MSVCRT.DLL already resided in the memory, even we change it to the new
version, the application still hangs. Since we have no way to take it out
from memory except reboot the machine.

======================================================================

More information from the submitter:
"The bug happen while loading an image. The Java method is being called
is: getDefaultToolkit().getImage(URL). We tried to reduce the size of this
program to make a simple test case, but the bug is unreproducible in the
simple Java test case."

more technical inforamation from Oracle:

so far this bug only happened when we ran a big application. There is no
small java test case that can reproduce this bug. But everytime, the
application is hung at the same place (trying to load a new image). Here
is the thread dump that you asked:
