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)

Using JDK 1.1.7B or JDK 1.1.8 or JRE 1.1.8
on WinNT 4.0 (SP5) the following source code
works fine.

But if I switch to SDK 1.2.1, SDK 1.2.2,
SDK 1.3.0 or JRE 1.3.0 an access violation occurs.


--[begin source]--

import java.awt.*;

public class TestGui extends Frame
{

  Menu myMenu1;
  Menu myMenu2;

  public TestGui()
  {
this.setTitle("Try to resize this frame!");

this.setSize(300, 300);
this.show();


MenuBar myMenuBar = new MenuBar();
myMenu1 = new Menu( "DemoMenu1" );
myMenu2 = new Menu( "DemoMenu2" );

myMenuBar.add( myMenu1 );
myMenuBar.add( myMenu2 );

this.setMenuBar( myMenuBar );
  }
  

  public void changeMenuItems()
  {

myMenu1.removeAll();


for ( int i = 0 ; i < 10 ; i++ )
{

MenuItem myMenuItem1 = new MenuItem( "DemoMenuItem" );
myMenu1.add( myMenuItem1 );

}

  }

      
  public static void main(String[] argv)
  {

TestGui myTestGui = new TestGui();

while (true)
{

myTestGui.changeMenuItems();

}

  }


}

--[end source]--


After moving or resizing the frame
I get this console output:

#
# An EXCEPTION_ACCESS_VIOLATION exception has been detected in native code outside the VM.
# Program counter=0x5005c632
#

and a dialog titled
"java.exe - Application Error",
containing the "stop" icon (red circle -w- white X)
and the text:
The instruction "0x5005c632" referenced
memory at "0x00000002". The memory could
not be "read".
Click on OK to terminate the application
Click on CANCEL to debug the application

If I debug this error I get the info:
Access Violation in java.exe (AWT.dll)

On Solaris 2.8, Linux Redhat6.2, the application causes to
hang the user interface.
