I'm not sure of the current numbers, but I know that previously we did comparisons and the monolithic jar was faster at startup (and smaller at download since we pack200 the whole thing), but that analysis may have been with WebStart (since that is how the 1.x platform shipped), and not with the installer variety. Igor do you know?

> Is the JDK modularization (Jigsaw) going to influence your structure?

Definitely. From a project perspective I think we're more or less there (ie: our source "modules" already exist and are fairly well decoupled and so forth), so when Java 8 modularity is far enough along and we're past 2.2 and working on 3.0 we'll start using Java 8 modularity.

> I think there are people enough who can, and would be willing to, help out with Maven / OSGi modularisation (since we know diddly about Jigsaw, I can't comment on that).

That would be good!
