Your assumption is incorrect.  Java doesn't handle hot-swapping
automatically; the application (or the environment it's running in) must
make use of the redefineClasses() method of the
java.lang.instrument.Instrumentation interface.  JBoss has code to do
this (part of its AOP implementation), but Tomcat itself does not.
JVMTI agents available with Eclipse, NetBeans, etc., may be able to do
it, but I can't say I'm familiar with them.
