JControl and JLaunch

Please advise on following opinions whether they're right or not.

On windows platform,

1. Each Java instance has its own JControl process. (1:1)

2. For Java Central Instance, there are at least three JLaunch processes (Java dispatcher, Server, and SDM)

3. For Java Dialog Instance, there are at least two JLaunch processes (Java dispatcher, Server)

Thanks.
