    [ https://issues.jboss.org/browse/JBIDE-10438?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12649701#comment-12649701 ] 

henk de boer commented on JBIDE-10438:
--------------------------------------

Investigating the html page a little bit further, I found that the following smaller page still causes the hang:

{code}
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

<html>
<head>
	<title>some title</title>
</head>

<body>

<script type="text/javascript" language="javascript" >
// A comment

function GetCookie (name) { 

  while (i < clen) {

  } 

return null;
}

</script>

</body>
</html>
{code}

However, the following does not hang:

{code}
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

<html>

<body>

<script type="text/javascript" language="javascript" >
// A comment

function GetCookie (name) { 

  while (i < clen) {

  } 

return null;
}

</script>
{code}

And neither does this:

{code}
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

<html>
<head>
	<title>some title</title>
</head>

<body>

<script type="text/javascript" language="javascript" >
// A comment

function GetCookie (name) { 

return null;
}

</script>

</body>
</html>
{code}

So it seems to be a combination between the while loop (which contains the XHTML reserved {{<}}) and the head tag.
