When you have a problem like this, you might find something pertinent in the
changelog; however, nothing popped out at me when I looked.

Hmmm... I tried this simple JSP file under 6.0.20 with no problems:
<html>
<%@ page session="false" import="java.util.*"%>
<%!
LinkedHashMap<String, String> menuItems = new LinkedHashMap<String, String>();
public void jspInit() {
menuItems.put("testKey", "testVal");
} %>
<body>
<p> testKey: <%= menuItems.get("testKey") %>
</body>
</html>
Perhaps there's a problem with whatever .jsp is pulling in the .jspf segment.
Might try setting the system property:
org.apache.jasper.compiler.Parser.STRICT_QUOTE_ESCAPING
to false to see if that has an effect.

Whoever suggested that is clueless about how classloaders work - that's an
extremely bad idea, always. Also note that Tomcat has not required the use of
tools.jar since 5.5 came out.
