In Java the motor safety stuff is enabled by default only for the RobotDrive class. Those messages are because you aren't updating the RobotDrive values often enough for the default timeout.

For example, if in some autonomous code you do:

drive.arcadeDrive(1, 0);
Timer.delay(1);

The 1 second delay will cause the motors to not be updated and you'll get lots of those messages.
