Answer 1

java.lang.NoSuchFieldError: ALLOW_FINAL_FIELDS_AS_MUTATORS

This makes it sound like you're picking up an old version of Jackson from somewhere. PartitionsLoader references MapperFeature.ALLOW_FINAL_FIELDS_AS_MUTATORS while initializing a static member field. If the version of MapperFeature that you pick up at runtime does not have this field, the resulting exception will cause the class initialization process for PartitionsLoader to fail. Subsequent attempts to reference the class will then throw the exception you're seeing.

ALLOW_FINAL_FIELDS_AS_MUTATORS was added in version 2.2. Which version are you picking up?
