win32: Assertion failure awt_Component.cpp line 1358

I'm getting assertion failures at awt_Component.cpp line 1358 occasionally
with the BeanBox while running with java_g. This is with vanilla JDK 1.1.1

Here's the source line where the assertion fails:

    Hjava_lang_String* AwtComponent::GetItemString(Hjava_awt_Component *target, long index)
    {
        Hjava_lang_String* str = (Hjava_lang_String*) execute_java_dynamic_method(EE(),
         (HObject *)target, "getItem", "(I)Ljava/lang/String;", index);
>>>> ASSERT(!exceptionOccurred(EE()));
        return str;
    }

And here's the windows backtrace:

_assert(void * 0x01f242e8, void * 0x01f242b4, unsigned int 1358) line 252

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

OK, I added in a exceptionDescribe to awt_Component.cpp, and this shows that the
offending EE() state was:

Exception in thread "AWT-Windows"
java.lang.ArrayIndexOutOfBoundsException: -1 < 0
        at java.util.Vector.elementAt(Vector.java:326)
        at java.awt.Choice.getItem(Choice.java:100)

------------------------------
We recently found an assertion failure that looks like JavaSoft Bug
#4042898. The description indicates that the problem happens in the
BeanBox. We have two very small sample programs that expose the same
problem in JDK 1.1.2 on WinNT 4.0 SP3. We have no means of adding
additional comments to the bug report so I'm using this mechanism so
you might add this additional information. We hope that providing
these simple samples it may improve the likelihood that the problem
will be fixed sooner.

Here are the programs:

import java.awt.*;
import java.awt.event.*;

public class ChoiceBug {
    public static void main(String[] args) {
        Frame f = new Frame("Choice bug");
        f.setSize(200, 200);
        Choice c1 = new Choice();
        c1.setSize(100, 24);
        f.add(c1);
        f.pack();
        f.show();
    }
}

and

import java.awt.*;
import java.awt.event.*;

public class ListBug {
    public static void main(String[] args) {
        Frame f = new Frame("List bug");
        f.setSize(200, 200);
        List l1 = new List();
        l1.setSize(100, 24);
        f.add(l1);
        f.pack();
        f.show();
   }
}

Here are some example output using java_g and jdb:

*** Running under java_g, I get the following:

*** Running java_g -tm generates a 122MB(!) method trace file.
 Grepping for getItem yields these lines in the file:

# AWT-Windows [ 2] | | < java/awt/Choice.getItem(I)Ljava/lang/String;
