Looking for a decent Plugin API/Infrastructure

I'm planning to support dynamic plugin loading for a project of mine.

It is important that the plugins will be able to load/unload during runtime and it would be a plus if it is possible to communicate between the plugins (i.e. have dependencies).

I've been looking at http://jpf.sourceforge.net/index.html but it seemed a little weak.

I have also been looking at http://www.osgi.org/ but that seemed a little to big :)

now there is this new jsr-277 too http://www.jcp.org/en/jsr/detail?id=277

Could someone please help me deciding?!
