@Bean
		public FormattingConversionService conversionService() {
			return new DefaultTupleConversionService();
		}
Illustrates the impact of creating a {@link DefaultTupleConversionService} for each
instance of Tuple.  The recommended approach is to either use the default instance or
configure a customized version that is created as a singleton within the context of
the module it's used.
