Isn't all that already adressed by the VM/GC and GC/VM interfaces posted
by Weldon Washburn [1], [2] some time ago? (I'm not sure if this is 
helpful, I didn't really read the BootJVM code, so please don't hit me
if I'm wrong). If not It might be helpful starting a WIKI - page which 
describes the BootJVM architecture/interfaces/..., although I guess some
of that is covered by the API docs too.
