I'm not entirely sure how your project is composed, but I ended up
having to create my login modules as fragments for the classloader
within the primary authentication plugin to resolve the classes.
Although I'm simplifying things a bit, I essentially had the following:
- authorization bundle/plug-in that performed the JAAS
- login module strategies composed as fragments to reduce coupling,
allow equinox bind them to the parent plug-in if available in the
install and be visible to the classloader of the authorization bundle
This seemed messy but it allowed me share a login dialog based on
Eclipse SWT between RAP and RCP installations. Despite working through
the classloader issues, I did eventually discover that creating a dialog
within a LoginModule would prevent interaction with the RAP application
by a given person using multiple browser instances until the login phase
succeeded. To get around this, within a RAP execution context, I present
the dialog then pass the credentials along to JAAS vs. have JAAS open
the dialog internally.
Did that make any sense?

I didn't really want to call the dialog outside of the JAAS framework.
Unfortunately, I had to under RAP since I was seeing that weird
deadlock-like issue. If you do something similar and don't have that
issue, let me know how you accomplished it.
BTW: Calling it from within JAAS under an RCP application worked fine
for me. Under RAP, it would open, I just couldn't log in from other
browser instances while the dialog was showing. I can't remember now if
it was limited to the user with the dialog showing or all users
attempting to log in. I do know I really didn't notice the problem till
I deployed it (probably because I'm in debug most of the time and not
trying to create multiple instances of the application in other browser
