My understanding is that Jackson uses by default its own naming convention, which is very close, but not exactly the same, to the Java Bean naming convention. A MapperFeature option, MapperFeature.USE_STD_BEAN_NAMING, was added in Jackson 2.5.0 to tell Jackson to use the Java Bean naming convention -- see Jackson Issue 653. For backward compatibility, the default value for MapperFeature.USE_STD_BEAN_NAMING is false.
