WLS 10 Release Notes

Hello all,
One doubt in WLS 10 Release notes at
http://e-docs.bea.com/wls/docs100/notes/new.html
In JSP support this page named five packages but only show four:

"Consistent with the JSP 2.1 specification, JSPs now implicitly import only
the following [b]five [/b]packages: java.lang.*, javax.servlet.*,
javax.servlet.jsp.*, and javax.servlet.http.*. If you have existing JSPs that
implicitly imported other packages, you must now import them explicitly."

So, what is the last package ?

Thanks in advance
