Ludovic Praud opened SPR-11354 and commented
I've tried to migrate my project from spring 3.2.x to 4.0 following #15865 comment https://jira.springsource.org/browse/SPR-11240#comment-97549.
But it turns out that I have a compatibility problem using FormattingConversionService.addFormatterForFieldType which throws a java.lang.IllegalArgumentException: Type must not be null.
I've created a reproduction project, see the given reference URL.
Affects: 4.0 GA
