There will be absolutely no issue because each launch configuration used to
launch a server is a dedicated one, with its own classloader.
The jars are not accessed from the Apache DS plugin jar, but they are copied
in the plugin's folder in the workspace of the application.
I took a look at what was done in WTP before building the Apache DS plugin
and I followed almost the same architecture.
So, don't worry, on that part of the game, we're completely safe... :-D

This will require a certain amount of work to get the Apache DS modules as
OSGI bundles I think. I remember discussing about that with Alex when we
were in the train back to Paris from ApacheCon Europe 2007. I think this is
something we'll need to do one day, because OSGI is so cool when it comes to
activating/de-activationg modules...
