FULL PRODUCT VERSION :
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)
A DESCRIPTION OF THE PROBLEM :
Whenever one uses HTMLDocument.insertBeforeEnd(element,
"<BR><H1>foo</H1>"), the break tag will be inserted,
followed by a </BODY> element, the <H1>foo</H1>, a <BODY>
element and then follows the element specified in the method
call. This effectively creates an additional body element,
with the break tag inserted into the first body element, the
specified header inbetween the first and second element and
the element which was passed as an argument resides in the
second body.
For example:
<HTML>
<HEAD>
</HEAD>
<BODY>
<DIV></DIV>
</BODY>
</HTML>
after calling htmlDoc.insertBeforeEnd(divElement,
"<BR><H1>foo</H1>") becomes:
<HTML>
<HEAD>
</HEAD>
<BODY>
<BR>
</BODY>
<H1>foo</H1>
<BODY>
<DIV></DIV>
</BODY>
</HTML>
If you substitute <H1> for <PRE>, the same happens, but if
you substitute it for <B>, it works correctly. Also if you
insert the <BR> and the <H1> in two separate calls, it works
correctly.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Compile the source code given below.
2. Run it.
3. Be amazed at this output:
1:
<html>
<head>
</head>
<body>
<h1>
foo
</h1>
<br>
<b>bar</b>
<div id="Java Bug Id 4496801 workaround">
</div>
</body>
</html>
2:
<html>
<head>
</head>
<body>
<h1>
foo
</h1>
<br>
<b>bar</b><br>
<h2>
foo2
</h2>
<div id="Java Bug Id 4496801 workaround">
</div>
</body>
</html>
3:
<html>
<head>
</head>
<body>
<h1>
foo
</h1>
<br>
<b>bar</b><br>
<h2>
foo2
</h2>
<br>
</body>
<h3>
bar2
</h3>
<body>
<div id="Java Bug Id 4496801 workaround">
</div>
</body>
</html>
EXPECTED VERSUS ACTUAL BEHAVIOR :
It should not create a second body element and insert the
HTML between the 2 body elements.
REPRODUCIBILITY :
This bug can be reproduced always.

Element div = doc.getElement(BUG_ID);
doc.insertBeforeStart(div, "<h1>foo</h1>");

// with the <b> tag it works fine

div = doc.getElement(BUG_ID);
doc.insertBeforeStart(div, "<br>");
div = doc.getElement(BUG_ID);
doc.insertBeforeStart(div, "<h2>foo2</h2>");
// when inserting the <br> and <h2> separately, it also works fine
sw = new StringWriter();
hw = new HTMLWriter(sw, doc);
hw.write();
System.out.println("2:\n" + sw.toString());
div = doc.getElement(BUG_ID);
doc.insertBeforeStart(div, "<br><h3>bar2</h3>");
// inserting a <br> and a <h3> in one call, triggers the failure
sw = new StringWriter();
hw = new HTMLWriter(sw, doc);
hw.write();
System.out.println("3:\n" + sw.toString());
}
}
---------- END SOURCE ----------
CUSTOMER WORKAROUND :
Insert the <BR> tag in a separate method call.
