Subject RE: [PATCH] Iteration tags do not synchronize scripting variables after doStartTag

Actually, the above has been too simplistic, because it does not consider the
case where BodyTag.doStartTag() returns EVAL_BODY_INCLUDE and
doInitBody() is not called, giving the container no opportunity to
synchronize the variables before the body of the tag.

I've talked to the JSP 2.0 spec lead, who is going to clarify the spec
as you suggested.

I've also applied your latest patch.
