If the tags (action elements) are nestled, code is generated to make sure a unique
instance is used to handle each occurrence. It doesn't necessarily mean that new
instances are created for each action, since the JSP container may use a pool of
instances to improve performance.
But in your example, the action elements are not nestled, so it shouldn't matter
if the same or different instances are used. A tag handler can not keep any local
state after the end tag anyway. If the tag handler creates some information that
needs to be available after the end tag, it should save the information as a
variable in an appropriate scope (page, request, session or application).
