What's wrong with Element Construction Set
(http://jakarta.apache.org/ecs/index.html) ?
IMHO the whole point of MVC is to separate presentation logic from business
logic. Your solution seems to only abstract html construction via java
object manipulation. There's much more to MVC than just
themselves. Though I haven't planned
it, its possible that these objects at a latter stage will render
something
else instead of Html.

I used almost every version of TC since 3.x to 4.0. Yes, I had problems
starting it and moments of frustration, but all issues turned out to be my

Tomcat is a _reference_ implementation.

TC is pure Java. Java has no methods that can force system shutdown.
The way to do it from Java is JNI. Search for native or loadLibrary
in deployed web applications to see if someone is doing something funky.
Another possible way to do it Is Runtime.exec(), so search for exec also.

One option you have is to put the classes that actually cache things into
a common directory ($TOMCAT_HOME/lib or $CATALINA_HOME/lib). Such classes
are shared across web apps, so this should accomplish your goal of having
a single cache. They are loaded from a (common) parent class loader
somewhat related issue I've found with T3.2.2.
After class reloading the old class isn't GC'ed, is a reference to previous
class that's kept around somewhere? Actually I noticed it because I had a
cleanup thread running infinitely, and after the class reload I ended up
having two threads running.
I don't fully understand your setup from the messages you sent but if you
have a custom class loader then you should register webapp class loader to
be the parent of your custom class loader. So, if your custom class loader
lives in webapp directory its constructor should look like:
public class
