It looks like the STR are more complicated. I deployed this into a running TC7
container by simply copying jspc.war into the webapps directory and letting
autodeploy do the work.

After that, I received the above exception.

Then, I tried to access /src/Test.jsp and I got this exception:

SEVERE: Servlet.service() for servlet [jsp] in context with path [/jspc] threw
excep
tion [Servlet execution threw an exception] with root cause

After restarting the server, a startup autodeploy occurred and the page ran as
I expected it would (printing 4 list items with literal "${num}" as the text).

Then, when accessing /jspc/src/Test.jsp (the source of the JSP, no
precompiling), I get a different output:

Example Pre-compiled JSP

    Item #{1
    Item #2
    Item #3
    Item #4}

According to Konstantin, this is probably what I should have expected in the
first place.

Several funny things are going on, here.
