022/**
023 * The putSafe method on the JCS convenience class throws this exception if the object is already
024 * present in the cache.
025 * <p>
026 * I'm removing this exception from normal use.
027 * <p>
028 * The overhead of throwing exceptions and the cumbersomeness of coding around exceptions warrants
029 * removal. Exceptions like this don't make sense to throw in the course of normal operations to
030 * signify a normal and expected condition. Returning null if an object isn't found is sufficient.
