the class ConfigUtil method getDefaultValue.

/**
 * Get the default value of a configuration interface method. If a
 * {@link Default} annotation is present then that string is converted
 * to the appropriate type using the {@link TypeFactory} class.
 * Otherwise, for the type Foo, this searches for a FooDefault
 * annotation. If such an annotation is present then its value is
 * returned.
 *
 * @param configInterface The configuration interface.
 * @param method          The method.
 * @return The default value, or null.
