That was my first thought as well, until I remembered how stupid compilers
really are.
The JSP engine looks through your page for tags it recognizes. Anything else
is considered to be template text, and is passed through unchecked. For 0.92
engines, it recognizes things like <usebean> (without the jsp prefix). It saw
<jsp:forward>, concluded "this must be some new HTML tag I do not understand",
and sent it on to the output file where it showed up in your browser's text.
One of the reasons that the "jsp:" prefix was added in 1.0 was to allow the
compiler to be smarter than this. It can look at a tag <jsp:xxxxx> and
complain if it does not know what xxxxx is. But, if you omit the prefix and
just incorrectly use <forward>, I bet it would make the same mistake.
