###@###.###

The problem is reproducible with Java Plug-in 1.3.0-C and JRE built from
the current Merlin workspace. Netscape 4.7 and Internet Explorer 5.  

To reproduce open Test.html in the browser:

----------- Test.java ----------------------------
import java.applet.Applet;

public class Test extends Applet {}
--------------------------------------------------
----------- Test.html ----------------------------
<html>
<body>

The browser starts loading plugin. Then plugin crashes together 
with the browser.

EVALUATION Name: dsR10078 Date: 05/12/2000 ###@###.### This crash was introduced with the fix for 4038769 which adds support for undecorated Frames and Windows. Now AwtFrame::GetClassName() accesses the associated peer object. For embedded frames GetClassName() is called before the reference to the peer object is initialized. ====================================================================== The above evaluation is incorrect. The bug was introduced when the fix for 4284277 was introduced. richard.ray@eng 2000-05-12
