25 * <p>
26 * I'm removing this exception from normal use.

28 * The overhead of throwing exceptions and the cumbersomeness of coding around exceptions warrants
29 * removal. Exceptions like this don't make sense to throw in the course of normal operations to
30 * signify a normal and expected condition. Returning null if an object isn't found is sufficient.
