Board.java won't compile...Un

When first compiling the java classes, I got an error related to uncaught Exceptions in Board.java.  I don't quite understand how this worked for anyone as it is.

To fix this, I added try/catch code around line 91 to:

I2CBus bus = null;
try {
    bus = I2CFactory.getInstance(busId);
} catch (Exception e) {
    System.out.println(e);
}
device = bus.getDevice(ADDRESS);
