Igor do you know?
yes, for webstart based deployment single jar is clearly superior from 
the startup standpoint.

I am not sure that splitting into multiple jars helps startup much 
unless a lot of these jars are not used.
You mostly save on reading fewer data from zip directory but reading 
multiple files may be more expensive as you do not benefit from disk 
prefetching.
I am not sure what is current size of zip directory for jfxrt.jar but it 
is likely to be couple of hundreds Kb i think (and controls only part is 
smaller).
This needs to be measured again of course but my gut feeling we will not 
win much.
