Right, even though they're probably loaded in a ClassLoader that JUnit is using,
they're also loaded in a ClassLoader I create, along with other classes being
tested. My ClassLoader loads its own classes in preference to its parent's
classes, which is the opposite of what's normally done. It's kind of a cheat
the way it finds the classpath entries to create the ClassLoader, but it works
for my cases - JUnit run by Maven.

<div class="">On the other

And there is always
bytecode-manipulation.

again: JUnit is no

you could even base it
