[jsr294-modularity-eg] iJam

[Alex Buckley]

I would like to have a slight hiatus on this issue since Andreas is away 
at the moment and I haven't yet been able to talk with Stanley about how 
277 will handle the iJAM extensions.

My feeling is still that 294 should let 277 handle inter-module 
dependencies, including their impact on classloading. 277-approved 
annotations like @ImportOwn(...) and @SetSearchOrder(...) on a 
superpackage would be a fine thing, but would have no meaning to javac. 
As such, I think the iJAM paper is for our EG's information only.
