[ajug-members] multiple jar versionsfor one application

[Carl Hall]

You can't have 2 versions of the same jar in the same classloader because
they will collide.  First jar loaded by the classloader will be the one that
is available.  To have 2 versions of the same class, you'll need to change
the package or class name.
