having done profiling in OptimizeIt with tomcat +
JSTL, I can say with confidence it does reuse the
tags. How do I know?
I've ran profiles with jasper1 and jasper2. With
jasper 1 if I have say 200 tags in a page, it makes
200 tag objects. With jasper2, it makes one of each
tag. So if have say 20 <c:if> tags in a page, there's
only one.
if you look at the generated source in the working
folder, you'll see this. You can easily verify this by
running 4.0.3 with jasper1 and compare the source
generated. It looks like you're using custom tags
which you've written yourself. Whether your tags are
written to take advantage of tag pooling is another
topic.
