It appears that the time it takes to get a ultrasonic sensor reading with icommand takes 100-200ms. Is that normal? Here's the code.
time = System.currentTimeMillis();
reading = sensor.getDistance();
logger.info("time "+ (System.currentTimeMillis()-time));
Is this due to the communication latency from the PC to the NXT?

Yes, there's another workaround by using this command after open():
I'll probably take a look at the UltrasonicSensor code soon and make it work more like the leJOS NXJ code (for upcoming 0.5 version) which has the timing issue worked out.
