I fetched a NullPointerException with this call stack:

I tried 1.5, 1.5.1 and the latest version from CVS. They behave all the same way. The problem is that WebRequest.getWindow() returns a null pointer.
Here is the header of my HTML page:
<!--DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd" -->
<html lang="en">
<head>
<title>MessagePlus/Open</title>
<base href="http://localhost:8080/mpo-webclient/mpo-default-page.jsp">
<link href="/mpo-webclient/mpo.css;jsessionid=j16aaz8yh1" rel="stylesheet" type="text/css">
<script language="JavaScript" src="/mpo-webclient/mpo.js;jsessionid=j16aaz8yh1" type="text/javascript"></script>
</head>
Can anyone help?
TIA, Frape
Can you make a sample that I can run to duplicate the problem?
Well, it must be something trivial that I make wrong. Here is the code:
WebRequest req = new GetMethodWebRequest( "http://www.mydom.com/tt/tt.html" );
WebConversation wc = new WebConversation();
WebResponse res = wc.getResource( req );
System.out.println(res.getText()); /* just to verify the HTML */
WebForm[] forms = res.getForms(); /* BINGO */
and the HTML that I put onto an internal web server:
<html>
<head>
<script src="/tt/tt.js" type="text/javascript" ></script>
</head>
<body>just a test</body>
</html>
The tt.js file is just empty. And here is again the exception:
java.lang.NullPointerException

Removing the src attribute makes the exception disappear.
