[forge-dev] Forge 2.0 and OSGi

My feelings about this question are likely consistent with what the JBoss
AS team has to say about their OSGi story. The container can be OSGi
compliant, we just don't want to build it on OSGi. In a diagram, that looks
OSGi plugin layer
The general argument here is that OSGi is a fine target for
application-level programmers, but it has too much architectural coupling
for building containers (such as JBoss AS and Forge).
Therefore, I think a reasonable approach is to have an OSGi-compliant
plugin layer so that plugin writers can code against OSGi and be able to
have their plugin loaded as a bundle. This layer would be in addition to
the preferred plugin layer, which loads the plugin as a (JBoss) module.
As for how to create that OSGi-compliant plugin layer, I have no idea.
That's not my dept.
