Jackson doesn't follow JavaBean naming convention

[slopetown]

JavaBeans spec:
getUrl/setUrl => property name: url
getURL/setURL => property name: URL

Jackson:
getUrl/setUrl => property name: url
getURL/setURL => property name: url

JavaBeans(TM) Specification 1.01 Final Release
8.8 Capitalization of inferred names.
http://download.oracle.com/otndocs/jcp/7224-javabeans-1.01-fr-spec-oth-JSpec/
Introspector.decapitalize
http://docs.oracle.com/javase/8/docs/api/java/beans/Introspector.html#decapitalize-java.lang.String-

Background:

Ajax post data: URL=example.com
(Content-Type: application/x-www-form-urlencoded)
+
POJO: getURL/setURL
+
Spring MVC
=> HTTP 200 OK

Ajax post data: {"URL":"example.com"}
(Content-Type: application/json)
+
POJO: getURL/setURL
+
Spring MVC @RequestBody (Jackson Integration)
=> HTTP 400 Bad Request

Thanks!

I'll have to discuss this briefly on mailing lists, just because it is a backwards-incompatible change.
But I think it would make sense to be compliant with Bean name-mangling scheme.
So at most we may need to introduce a feature, to allow using existing scheme if needed to support legacy code.

Ok, ended up adding: MapperFeature.USE_STD_BEAN_NAMING (defaults to false) -- enable this feature and naming should follow standard JDK Bean convention (identical to BeanIntrospector.decapitalize()).
