your test case still requires lombok. please make a test case without other dependencies. i suspect lombok is generating a different getter name, but it’s hard to tell with your test case.

the code you show in legacyManglePropertyName is not supposed to be hit because the property name begins with a lowercase character (there’s a check further up). you can try USE_STD_BEAN_NAMING if you want, but i doubt it’s going to work

No full reproduction, closing. But I am 95% certain that in this case user needs to use an annotation to connect somewhat non-standard (wrt Bean naming) field name and getter/setter, to get Jackson to use and recognize specific JSON property name.
