If you do go with OSGi, you will have problems with classloaders and
deserialization.
To my knowledge, nobody has yet solved this (i.e. implemented a good
solution) in a decent way. The Eclipse buddy system is not "proper"
OSGi, IMO.
pax-wicket does "solve" this problem (using "proper" OSGi), but I have
never used their approach much even though I use the framework.
Here is a post about this by me with some interesting comments from

Good luck to you!

it is easy to create a pluggable application in wicket. all you need
is a registry of component providers, whether it be something like
spring [1], a custom registry like brix uses [2] or something more
advanced like osgi. the choice should be based on the featureset you
need. eg, if you need hot updating, classloader separation, etc, then
osgi is good. if not, there are simpler ways to achieve modularity [1]

modularization.

Hello,
I'm currently designing a new application. One of the requests is
to make it
modular. I found out that one of the possibilities to enable
loading of
modules while application is running is OSGi. Is there a tool/
plugin/guide
to accomplish this or are there any other possibilities of
accomplishing
same goal?
