The situation is not that simple. For example, the borderline between "general computation" and "embedded" as it is defined by Oracle is not clear at all. They say if your app controls some external "hardware", it makes your system embedded. Does sending a command over a serial line to an actuator from a Java app makes it embedded? Apparently yes. How about Bluetooth devices? A joystick? Controlling a router? Now, how about a rack stuffed with ARM units, are those embedded? They might be quite easily, depending on how Oracle interprets it.
