NPE from CodeInsightUtil.findStatementsInRange() with specific JSP scriptlets

Created: 13 Feb 07 22:05   Updated: 13 Feb 07 22:05
Component/s: J2EE.JSP
Fix Version/s: None

Original Estimate: Unknown Remaining Estimate: Unknown Time Spent: Unknown

Build: 6,703


 Description  « Hide
Get a JSP: 
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
	<head><title>Title</title></head>
	<body>
		<p>
			<%
				for (int i = 0; i < 10; i++) {
			%>
			<%=i%>
			<%
				}
			%>
		</p>
	</body>
</html>

Put cursor right before any of 2 "<%" tokens. Invoke main menu | code. Wait a bit - exception. See below.
I cannot reproduce it in simple cases, e.g. in case when the "for" loop is completely within the single scriptlet block.
