Argh, this is a bug! JSP 2.0 now recognizes ${...} as an EL expression,
so there are some special handling for $ in the parser. It got this
wrong, apparently.
I'll commit a fix to this as soon as I send this mail out. Note that
the workaound to this problem is to write
\$<jsp:getProperty name="login" property="username"/>
instead. Here, \$ is an escape for $. This is new in JSP 2.0.
Note also that this can now be written as
\$${login.username}
taking advantage of EL in tc 5.

This would not work, since parseXMLTemplateText deals only with
text in the body of <jsp:text> element.

Well, this is a good time to do that, now that Jasper in TC5 has
stablized. Ping me if you need help. :)
