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. > [Snip] > Regards, > Robin Regards, David.
