auto convert threaded to nio/event?

[raould]

hi,

unfortunately i'm only vaguely familiar with the science of it, but i
believe there are things like cps or trampoline techniques one can use
to convert threaded code to event-driven/nio/callback code.

might anybody know of tools which help do that to java code? i.e. i
have a big library that uses threads, and want to convert it over to
events style so it scales better.

thanks for any thoughts/leads,
