thanks for your response!
Well...I tried to use LockType.Shared but It doesn't let me to save setting
( The function "saveSettings" returned an error condition: "The machine is
not mutable (state is Running)")

Yes, The machine is running under my control (in theory), because I started
it up using java Main Api.
I really would like to change some setting while it is running but I don't
understand if it's possible.
