[news.eclipse.newcomer] Stack Overflow when typing JSP source annoys me

[exquisitus <agz@xxxxxxxxx>]

Hello,

When typing JSP source I'm getting the pop-up dialog with the following message:

org.eclipse.jst.jsp.core.internal.parser.JSPSourceParser: input could not be parsed correctly at 
position 816 java.lang.StackOverflowError

The source code, which I've been editing lat time was:
------------------------ begin ---------------------------
<%@ page language="java" %>
<%@ include file="/WEB-INF/jspf/jheader.jspf" %>
<sql:setDataSource var="DBConn" dataSource="jdbc/db"/>
<sql:transaction dataSource="${DBConn}">
<c:choose>
<c:when test="${empty id or fn:contains(fn:toLowerCase(param.action), 'as new')}">
 <sql:query var="qid">select GEN_ID(G_PRODUCT_ID,1) as id from RDB$DATABASE</sql:query>
 <c:set var="id" value="${qid.rows[0].ID}" scope="request"/>
 <sql:update>
   insert into products
     (id, name, kind_id, price, max_qty, img_url, description)
   values (?, ?, ?, ?, ?, ?, ?)
   <sql:param value="${id}"/>
   <sql:param value="${name}"/>
   <sql:param value="${price}"/>
   <sql:param value="${max_qty}"/>
   <sql:param value="${umg_url}"/>
   <sql:param value="${description}"/>
 </sql:update>
</c:when>
<c:when test=
</c:choose>
</sql:transaction>
-------------------------- end ------------------------
The cursor was after the unfinished `<c:when test=` tag (third line from the bottom). Error usually 
appears when I'm typing quite fast.

Please help me to get rid of that annoying bug.

Thanks,

Andrew
