PS2, Line 130:   public String getProviderName() { return "sentry"; }
> Can we make "sentry" a public static final String?
I dunno, in this case the magic string is returned as the implementation of the 
abstract `getProviderName` method.  IOW, the method itself kind of acts as the 
public contract for getting the name, and any other entity which wants to get 
that value should be calling the method (as opposed to accessing a public 
static constant).
